Ok, so I just got done bugging the mighty developer, coder god, Sylvain. The guy behind Truevision3D the engine N8 uses...
He just modified the engine so I could save out and load up physics bodies, instead of generate them from scratch every load... also, he gave me the idea to generate and save out a faster loading version of the blocks etc.
Things are loading so much more quickly, its like a dream, and i don't have to rewrite the whole game!!! :D
