New to game development?

Game jams are a great excuse to build your first game, play with a new game engine, or learn a new language. There are plenty of free, open source and “source available” engines to explore. Here are a few suggestions for some popular languages:

• JavaScript: you might be interested in Phaser or Sprig.
• Python: check out Pygame or Godot (Godot uses GDScript, which is similar to Python).
• C++ or C#: look at Godot, Unity, and Unreal Engine.
• Rust: you might like Bevy.
• Java: take a look at libGDX.
• Flutter: take a peek at Flame.
• Go: you might want to look at Ebitengine.
• Lua: check out LÖVE or Defold or LIKO-12 (especially if you like retro games)!

The Game Off 2026 Community is a great place to ask questions or look for teammates. There’s also a fantastic and friendly community-run Discord server
