Because I was horribly unprepared and only doing this on the spur of the moment, I've spent most of the first day screwdrivering a HaxeFlixel setup into place with IntelliJ and Tiled and going through part of the tutorial. I still think I can get something in for the jam; it'll be a modified rendition of some ideas that have been bouncing around for previous LDs but which I never properly implemented. It'll wind up being pretty cut-down, but then I'll know more about the engine, which is sort of the point right now anyway.

Wish me luck!
