Ummm I'm keeping the exact nature of the game under wraps because I like surprises. :) It's not an arcade-style game, though. I'm still feeling my way around the graphics libraries and such, so maybe I'll think about those soon.

It'd be cool if bmihulka ported his Emptris to the userland interface. If he doesn't I might give it a whirl after I'm done with my own game.

The main problem I'm having is that the GD graphics libraries aren't too quick. As things evolve it'd be nice if some assembler folks could string together some assembly libraries for graphics. GD works well for me but it's definitely not optimized for the SA1100.
