The goal of this game jam is to build a game that can be completed in 20 seconds or less. You'll have a full three weeks to build a 20-second game (keeping things low-stress).
Rationale
The first twenty seconds of your game are the most important (especially as an indie dev). It's the one chance you have to get someone hooked. This game jam will help you hone your skills and explore how to make those first twenty seconds of your game as compelling as possible. You can read all the details on the official game jam page.
