Novel Twist on Classic Game
My game is a twist on the classic game "Snake".

Chain Reaction
When you hit an abstacle you explode in a chain reaction, hopefully destroying all ghosts in the process.

Negative Feedback Loop
Not that directly implemented, but there is a decision to make how long you want to become before you detonate yourself.
Getting longer makes the game harder but at the same time makes it easier to hit all ghosts in your explosion.

Use of diversifiers?
This is also on the game page, a bit better formatted.

Community
Join the Trijam Discord and read the #rules channel!
I've been on the Discord server since before the Triple Trijam. There is no #rules channel, though. I've read #info, I hope that counts.
Play, rate, and leave a comment on every game submitted to the jam!
Working on it :D
Code
Upload the source code of your project to your game's itch.io page!
The source code is hosted at Github: https://github.com/TLochow/Snakebomb
There are even different branches for each of the three versions, if you are interested:
Version 1: https://github.com/TLochow/Snakebomb/tree/Version_1
Version 2: https://github.com/TLochow/Snakebomb/tree/Version_2
Version 3: https://github.com/TLochow/Snakebomb/tree/Version_3
Make a procedurally-generated game with functionally infinite levels (or an infinitely long level)!
Snakebomb features randomly generated levels.
Design
Make a game that uses randomness!
Randomness is part of the core design of Snakebomb. The game generates random levels, places the ghosts and the player randomly in said level and the cherry-bomb is placed randomly.
Accessibility
Make a game that can be understood regardless of what language the player speaks!
While this game features english text and the "How To" is in english it is also not very complicated and I'm pretty sure even somebody who doesn't understand english can figure the game out pretty quick.
Make a game that can be played with WASD, ZQSD, Arrow Keys, and IJKL!
All of these inputs are accepted.
Use a color-blindness filter to test your game's art and make sure it's clear for people with all kinds of color-blindness!
I used a filter and also asked a friend of mine with a red-green colorblindness about Snakebomb. We both agree that, while certain sprites appear as the same color (the snake and cherry in his case), all things behave differently enough that the similar looking color is not too much of a problem.
Meta
Make a game with a main menu! In a game jam! WOW!!
Snakebomb proudly boasts a main menu!

Did you have fun?
