this is a very serious game jam so there are obviously insanely high stakes. you can expect your life to begin fraying away before your very eyes should you fail.

you will be rated by your gamemaking peers, and by me, on:
enjoyment
creativity & theme use
visuals
audio
rules
no generative ai art or audio. i encourage you to not use ai to code, though this is impossible to enforce. this is a jam about making things, so please make the things. everything else is between you and your conscience
you can work alone or in teams of any size, on however many games you wish to submit
pre-existing code and licensed assets are okay. credit everything you didn't make in your game description
your game must run on web or windows with nothing but a keyboard or mouse with no extra software. games that require additional software/login will not be streamed or considered for my top picks
no nsfw, graphic gore, strong language, or other elements unsuitable to a general audience. i don't make the rules (i make the rules)
submitting a game gives me permission to feature it in a video and play it on stream because yeah
late submissions: you will have a 24 hour window after the deadline to fix last minute bugs and modify your game's page. after this, files are locked
