Hi everyone,
I’ve always found it a little hard to find game jams that really push me to put my technical skills to the test. Most jams focus on a theme or a genre, which is great, but there aren’t many that focus on how efficiently a game is built.
"Below is a great example of making the most with the least. This image was created by @KasumiDirect as a NES guide."

That’s why I decided to create 8biter Game Jam #1.
The idea behind this jam is simple: build a complete, playable game while getting as much out of the smallest possible file size. It’s inspired by the way early games were made under strict hardware limits, where every byte mattered and clever solutions were part of the fun.
Games are judged on familiar jam criteria like gameplay, visuals, audio, and theme use, with file size applied as a scoring multiplier rather than a hard limit. Any engine or language is welcome, and browser-playable builds are required so entries are easy for everyone to try.
If you enjoy optimization, technical problem-solving, or challenging yourself beyond just the theme, I’d love for you to check it out.
