I’ve been working on an open source orthogonal tile engine that uses Cocos2D HTML5 over the last couple months. I still need to add basic physics and a couple of other things. Hopefully I can get that done by Friday night!

Please let me know if you use the engine for anything or have any feedback on it. It is still a work in progress, so keep that in mind!
