I'll be joining Ludum Dare 40, using an open web framework as usual. I'll work from my RocketBoots open source JavaScript toolkit, using techniques I've honed in my many other games. Since some of my games and tests ran into some performance issues while using canvas (such as http://deathraygames.com/projects/galGen/) I'm considering combining in Pixi.js to take advantage of its fast WebGL rendering.
