I understand from the rules that you can start out with some personal code libraries as long as you make them freely available before the event.

I make own starting kit available here which contains a basic HTML5 game setup with canvas, game loop, sound/image loaders and other utility code for math etc. The starting kit also contains some Java code for creating a custom grid-based level editor with several layers and properties that can save levels in both XML and JSON. It doesn’t support properties yet but I might add that during LD22. There is also an Ant distribution script that concats all the code and minifies it.

Bye!
