Promotional Material

For the events I wanted to make some promotional stuff to give out such as stickers, mini prints or bookmarks as a little thankyou for playing my game and so they can find my websites and social media. I also need to make a really large (2m long) image for the banner to advertise my game, so that’s going to take quite a while. I would have liked to have gotten some made in time for hand in but it seems like time won’t allow that : ) So I’ll be working on that in the weeks leading up to the events.

But I wanted to just get some of my ideas down in sketches, so here are some rough doodles of what I was imagining and brainstorming some possible things to make.


I then took one of my banner designs and expanded upon it digitally. I added some creatures in the background and made the landscape more three-dimensional to lead to the eye forward. The colours were quite tough to get right, as I wanted a more dramatic look with more eye-catching colours so I had to tweak the colours from my game to be brighter and more contrasting.


I think it looks quite effective and interesting. I wanted to include a hint of the creatures and get across the stifling and eerie atmosphere of the surface.

I wanted to make a Tshirt to wear to the shows so I quickly cut a stencil of my logo and used some fabric markers I bought from ikea a while ago (came in handy like I thought they might) Now I am looking at it in pictures I’m thinking that it might look a bit like blood, but I don’t have time to change it now. But after deadline, I will probably add some details or something in other colours to make it look not quite so much like blood.


I was doing a bit of thinking about what kind of things I want to give out at the shows, like postcards, stickers etc. and decided that I want to collect donations for an environmental charity either by ‘selling’ prints for donations or a sort of giveaway where people would donate say £1 and be entered into a giveaway for a bigger prize like a commission or the handmade plushie of Digby I was planning to make. Originally, I was just going to print some postcards to give out for free but I think expanding to include some more special items and asking for donations instead would be a good way to hopefully raise some money for a good cause that’s relevant to the themes of my game, which I care a lot about : )


I also sketched a little plan for how I’m thinking I want to set up my booth. My game is going to be in one of the arcade cabinets that the Uni has, but I would like a table to show some of the concept art, sketches and things to donate for such as prints. My cabinet is going to be printed a sort of brick red-y orange, but I was thinking I might paint some details on it with acrylics or something, like a horizon or stars or clouds or something, just to make it look a bit more eye-catching.

I did some research into some environmental charities, mainly ones based in the UK. I want to pick a good cause to donate to, but it’s hard to pick between them.

I forgot to mention that a few weeks ago I had a go at making some little cards to give out to people with my info and the info for the London show. These aren’t proper business cards as I haven’t had time to work on those, and I’m thinking I want to invest in a nice domain name before I print them, to look more professional. Hopefully I can get some better business cards done for the London show, but these should be ok for the moment, just in case I get the chance to hand some out or I’m caught needing to give me details to someone easily.



Making of Documentary and Trailer Creation

I used Sony Vegas to create a short video that showed some of my inspirations, process and thoughts. I really enjoyed filming the footage and compiling it with the music. I asked Sam if I could use some of his music to accompany the footage, he has a lot of music that he has made over the years so I took a look through and found some that had the right kind of vibes for my game – kind of melancholy but not miserable.

I then made a short trailer for my game, a little compilation of some of the more interesting scenes to show the different areas and atmospheres. I used some more of Sam’s music.

Also, I filmed a playthrough of the game for anyone who can’t get it working for whatever reason or doesn’t fancy playing it : )

Here’s a little screenshot of what the project looks like in Sony Vegas. I find it’s a really easy and intuitive program to use and would recommend for people that aren’t that technologically inclined. Basically all you have to do is drag and drop. : ) I think editing videos is actually really satisfying and fun and I’m glad that I’ve learnt the basics so that I can use them in the future if I ever want to make any other videos, maybe for youtube? Who knows…

I also recorded myself going through my project file and explaining the different objects and rooms and how they all work. It might provide some insight? Who knows…

Here is the updated playthrough of my final version for hand-in. I updated a few things so it feels a bit more complete and professional.

Sounds, More Testing and Polishing


I arranged another testing session with some friends that knew nothing about my game, so they could be fresh eyes and give me some first impressions.

Here are some notes they gave me –

  •  Sometimes fall off the side of map – check that all collisions are there.
  •  Interesting art style and very atmospheric.
  •  Like that each bug has different personality, I don’t trust Sloan.
  •  Indicate what the button and key have changed in the world.
  •  Sufficiently disturbed by some scenes.
  •  I got the idea that the people in the group are not satisied with their life and need to break out.
  •  The mystery is what happened to the farmers and why the surface is really dangerous. Something to do with pollution and environmental issues.

I’m glad they got what I was aiming for, such as the mystery and feeling a bit disturbed by some of the scenes, which is what I wanted. I like that they liked the art and how different the characters are. I do need to tweak some of the progression elements such as the button and key to let the player know what is happening. I quickly fixed the collision blocks on the maps so players wont fall off now : )


I used some ambient sound generators like Moodil and A Soft Murmur to work out the kind of mood I want in my game. For now, I am going to be using these sounds in my game but obviously if I were to release this game fully I would record my own sounds as I wouldn’t want to infringe on any copyright. I would not be charging any more for my game any way so I’m not sure what that would mean, but just to be safe I would want to create my own.

I had a lot of fun playing around with these sounds to create interesting atmospheres for each of the areas in my game. I liked the sound of the singing bowl as a sort of musical aspect but not too tuneful or repetitive, I think it sounds quite lonely and eerie as well. I used some wind and thunder noises for the surface and some quite murmuring of voices for Chasm city. For the under-lake rooms, I used a very quite wave noise, some static, some thunder and some more of the singing bowl to make a mysterious, claustrophobic soundscape.

I also used Bfxr to make sounds for the interaction and doors. It’s a cool online editor for traditional sounding game sounds. I fiddled around with it for a while and came up some decent sounding effects. They add a bit more immersion and make the game feel more responsive.


I also used the footsteps track from Moodil and edited it with TwistedWave online sound editor to make it a bit faster to fit better with Digby’s footsteps, about 115% speed. It is serving its purpose well enough at the moment but I would like to make a custom footstep sound effect better suited to the environments.


I made some sounds for each of the NPCs, like I planned to do ages ago : ) I just used Bfxr to make some lo-fi sounds that I felt reflected their personalities. Sounds like these are very reminiscent of old school games with 8bit soundtracks or the original Pokémon noises, but I think the lo-fi quality suits the pixel style of the game. You can hear them in action in the playthrough below…



I added some more details to some of the backgrounds I felt needed some.

I added the much needed background detail to this market hall. I wanted to show the kind of society that lives here. Everything is very natural and hand-made, and they have to make do with the limited materials they have, so their society is quite primitive in terms of technology.
A close-up of the market stalls. I used lots of earthy colours that are quite saturated to show the colourful nature of the market, but the colours are quite dull to reflect the naturalistic way of life and the dark, dank feeling of the caves.
I added a few more details to the houses here in Digby’s neighbourhood. I also added a few people up on the layer above to make it feel more like an actual place people lived. Although there are not many and they don’t look too happy, and the houses are cramped and ramshackle as this is a poor neighbourhood.

I also updated these two backgrounds to have a more refined style. I was originally going for a more geometric look with the environments, but as I went on with drawing them they gradually got more naturalistic and detailed which I actually prefer in the end, as it adds more believability and immersion. The strangeness is more in the stylized characters and the slightly off block colours.

New version – I changed the shape of the clouds and landscape contours to be more natural and less straight and sharp, also added a sun with some sun-flares : )
Old version
New version- added more definition to the horizon, more shape to the clouds and a little feint sun.
Old version
An updated look at the mushroom lamp in Digby’s room. : )
I added those shadows I talked about in a previous post. I made a sort of mask of black shadows and lowered the opacity of the object in Game Maker to give the effect of shadows. If I had more time I would have liked to animate some light effects but at the moment I only have time to give the allusion to some : /


When I uploaded my latest build on I received some feedback from a user with some really helpful points on how to make my game better. Some things will have to be worked on after the deadline for the shows though as I’m not sure I have time. But I will definitely work on including more interactions and things to look at, which was one of their main points. Also adding an ending screen to finish the demo and thank them for playing, this will probably be quite easy to do, but if I can always do it for the shows in the end.

Ok so I just added an end screen that will come up when you press E, which at the moment would have to be done manually. But ideally I would like it to fade up after a certain amount of time but I’m not sure how to make things happen in time in Game Maker so I will have to research that. But for now I can just manually press it when they have reached the last scene and give them a postcard and some stickers or something as a thankyou for playing : )




Setting up the Journal mechanic

I really enjoy ‘journals’ in games that are gradually filled out as the main character goes on their adventure, and I thought this idea would fit well with my game idea to serve as a kind of travel log which will hopefully be another entertaining level of storytelling.

Here’s the design board I made previously which I will be using as reference and inspiration whilst making the assets. I’ll be using the same method of code variables that I used to set up the doors and obstacles in the game. So once the player has encountered something in the world a drawing will appear in the journal along with a little comment from Digby.


Also, I have been reflecting on one of my relative’s comment during testing that I should include larger more detailed images of the characters as they would like to see them closer up. I have been thinking about how to incorporate more character details and I decided that I could make a second journal page that you can flip to that shows Digby’s impression of each of the other characters as well as some drawings of them. I thought that would be quite a characterful and cute way to show more personality. I also would like to add some larger character portraits when interacting with them in dialogue, but I have yet to decide how that should be yet, if I have time to implement it.


I created two journal page backgrounds and set them up so that they would serve as a kind of pause screen, so by pressing a key you can go to the journal and then pressing the left and right keys flips between the pages and another key returns the player back to where they are in the game. At the shows, I will encourage players to keep checking the journal so see if there is new content.


Here is what the journal looks like when it is filled, I drew the images seperately and created them as objects which are created in this ‘room’ when the player reaches certain landmarks. I like how it looks so far, I just want to add some little notes around the images to give the players a little more insight into Digby’s thoughts.


And here is the finished version with notes. I didn’t include a note on the top left pic as I felt like Digby wouldn’t know what to think about the fact that there were another people different from themselves. They are an upbeat character and I think facing that sight would leave them pondering and unable to form thoughts.


Here is the finished character page. It would be updated when Digby and the team first reach the hub room and settle down. I want the sketches to look like observational drawings, with some being candid and otto trying to sit still for Digby to draw and feeling awkward. : ) Hopefully I got some character and personality across. In the final game, there would be many more pages with more sketches throughout the course of the player’s journey.



Planning, Cutscenes and Backgrounds

I completed all the cutscene frames so that the game’s premise is set up and I can work on the later sections. I used a more detailed, higher-resolution pixel style to better convey what I wanted. I kept the shapes simple and focused on texture and colour in the landscapes and expression and body language of the characters, to hopefully portray a lot with a streamlined style.

The characters taking the lift up to the surface. I tried to show their individual feelings about going up to this unknown place.
Digby’s first view of the surface. I wanted it to look quite impressive but also pleasant and have an atmosphere of freedom and expansion.
The next cutscene takes place when a sandstorm hits the group, I wanted to show the unpredictable and hostile nature of the surface, that one minute it can be almost pleasant, the next it’s a dangerous, wild place.
The group make camp in their tiny tent and we can see the silhouettes of mysterious creatures behind, are they curious about the newcomers? or something more sinister? I wanted to silhouettes to be very feint and almost easy to miss.
After to the sandstorm the landscape is transformed and the tent is half submerged in sand.
Digby looks out at the aftermath of the sandstorm. I would like to include more close-up character cutscenes in the full game, but for the time I have, I need to complete more integral parts first, perhaps if I have time…
Digby realising that the landscape has changed. The sky has changed again and looks more calm and serene with the gentle purples and blues, to reflect the calm after the storm.

Here are some of my preliminary plans for how the surface map will work and which areas to create, and some sketches for the cutscenes. My sketches are really messy but I know what they mean : )



After expanding on my initial level plan, I started work on the remaining backgrounds using the same technique as I used when creating the backgrounds of my initial test build. I do feel that, as I have completed them, the later ones have gotten somewhat more detailed than the earlier ones and I will have to go back and tweak some to make the overall look more cohesive.

The hub room as the team first find it. It would get gradually more developed throughout the course of the game, with more homely touches and expansions.
This is the first stage of the hub room being made more of a home.  
The team unpack some mushroom lights and sit around them. Sloan is already feeling quite at home, the others not so much.
Whilst Mal is off in the corner sulking.
The blocked passage that leads further into the cave. Otto can unblock the way if you ask him.
A little oasis found behind the landslide. Now the team have a thermal pool to relax in. This is where Digby first encounters one of the ‘creatures’, it appears to be dead though. I wanted them to be slightly robotic looking but also reminiscient of bugs and animals, whilst also looking quite cute when they are not massive with creepy glowing eyes. 
The cave by the lake, with a nice view. The walls and floors are embedded with chunks of bright plastic. I wanted this area and the lake area to look almost picturesque but not quite right.
The water is slick with petroleum and the land in the distance is in fact a huge rubbish heap overflowing it’s banks and leaching into the water.
The key the player finds by the thermal pool will open the door to this more man-made area. I wanted it to look quite slick and ‘modern’ but a bit sterile and industrial. Is it a luxury minimalist under-lake house? Or some kind of facility?
Further in, the water above gets darker and murkier. I think I want to add a darker overlay for some shadows, so I will work on that later and see how it looks. I think it will probably increase the gloomy oppressive atmosphere, but we’ll see!
The creepy person-encased-in-molten-plastic room. I wanted it to look quite mysterious and like a tomb. The body is much larger than Digby and that should raise some questions and mystery for the player. 
Just some dark tunnels leading to the rubbish tip above. The light is still slightly purple but very feint as plastic residue has built up above.
The final area! A huge rubbish tip overflowing with waste that hasn’t managed to decompose in all the years since the collapse of the past civilization. I used dull colours with some brighter accents for the coloured plastic, and some rather unnatural colours for the sky as I wanted it to look like it’s warped by fumes from the plastic.
In the distance you can see some of the large creatures roaming the desolate landscape. They are far enough away that they might not have noticed Digby, but that doesn’t meant there aren’t more hidden amongst the waste.
I wanted the final shot of the game to create more mystery for the player and bring up more questions. I chose to show the carcass of one of the beasts that looks part mechanical and part biological  with the various bones surrounding it. I wanted the player to get a closer insight into the world but that might leave them more curious and confused than before.


Working towards MVP

My aim now is to complete a rough version of the entire game, setting up the rooms, cutscenes and interactions and slowly upgrade it to final assets. I find myself wanting to make the game in a linear fashion, so that it looks somewhat presentable but I really need to get all the foundations down so I know the structure of the game and the full story.

I am currently working on blocking out all the rooms and sketched the cutscenes I want for the first transition from Chasm city to the surface. I’ve set up rooms in Game Maker that mimic cutscene frames (the easiest way I could think of to manage it), and with the fade to black between frames it looks quite decent.


I sketched out the basic features of the next few backgrounds to get working.

I worked on some of the main backgrounds as a break from coding (also because I couldn’t help myself and wanted it to look somewhat atmospheric). They aren’t quite finished as I need to add more details and objects to interact with but the general look is there. The colours I’m using are slightly unnatural and quite saturated to add the slightly strange and hostile atmosphere. I want it to look a little radioactive and hazardous.

The first image is the player’s first look at the surface so I wanted it to seem quite pleasant and get progressively more hostile looking and dangerous.

The second image is when the world gets a little stormier and more angry before the sandstorm hits (which will be shown in cutscenes). I emphasised the purple, bruise-like colour and the landscape gets spiker to look more aggressive.

The third image is after the sandstorm, in the morning. The previous landscape is transformed and the landmarks (when there are some) will be gone. The player enters the cave which will be established as a new settlement.

The last image is past the new hub-cave, down the rock formation towards a lake or perhaps a sea as you can’t see the other shore, only the heaps of partially decomposed plastic. The plastic has turned the water toxic and given it the trademark rainbow colours of petrol-spill. I received some feedback from my brother about how the plastic mounds look like more land and perhaps to add brighter colours to make it more obvious. I was aiming for it to look like the colour had leaked out over the years but it should look more obvious, so I will work on that.

I have added new instances for the NPCs in the new areas, with new dialogue lines which will hopefully reveal more about their character. Once reaching the hub-cave, they will stay there and will have new things to say after Digby explores more areas of the world.

Here is a link to a video of how the current build is looking. If you want to have a go at it then I have uploaded it to too – here
