Pretty cool so far. First time I hear about this Monkey language. I'm guessing you're using the miniB3D module?
Actually, it's all fake 3d, done with sprites. Old school! I'm trying to keep it limited to something an early 80's computer could do , although I'm using probably more colors than I should. Monkey is pretty simple and is great because of its simplicity, but the issue is that getting the basics (a hierarchy graph and entity system, collisions, etc.) can be a pain, since it doesn't come with a default engine.
