The STFJam series is a series of yearly monthly, week-long game jams that I started because I had no idea what else to do. They usually start at the 8th of the month and judges are given 24 hours to vote by criteria

Helpful tips:
- Keep the splash! (It might disclose your engine)
- Make it open source! (Put it on GitHub, so if I find any bugs, I can analyze your code and probably make a detailed essay on how the bugs work and how to reproduce them)
You are encouraged to:
- Use an unfamiliar listed engine or DAW (You are allowed to learn new engines, challenge yourself a bit!)
Wanna challenge yourself? Here are some challenges you can try:
- Don't use any external dependencies, unless it comes with the engine
- Make everything yourself, except the engine
