okay so here's the deal; I'm trying to write a simple game that uses alot
of the Aliens code and the some tiling code from twitch. it was working on
pygame 1.1, but it freezes up when i installed 1.2. it seems to blit the
background to the screen and then it freezes.
oh and i get a bunch of these errors
libpng warning: Incomplete compressed datastream in iCCP chunk
libpng warning: Ignoring truncated iCCP profile. but i use to get these errors when it worked
well here's the code:
