very nice, its for games like this that i nag for mesh support, a simple mesh inplace of a 3d box would make N64+ quality games possible.
you could of made good use of families instead of making a seperate action group for your 2 types of objects (sprites and rotating geometry)
your game made me revive my 3d platformer, and great job on it!
oh ya, what exactly do you need the registry for?
is it for that KIA thing? because i cant play your game again, which is kinda lame
