What is libGDX?

libGDX is an open-source, cross-platform game development framework built in Java:

Unlike many popular editor-based platforms, libGDX is entirely code-centric, offering developers fine-grain control over every aspect of their game. It is the perfect place for exploring ground-up implementations, built on top of lightning-fast OpenGL, and distributable to Desktop, HTML, Android, and iOS.

This jam is over! Please stay tuned for the video review. Until then, please play the games linked above!
