Please download the latest release of my game, it took me about 2-3 weeks in SDL and if you ever downloaded 0.5 you'll see this is a much improved version:
If you have MSI (XP and 2000 always do, otherwise you likely don't)

Otherwise the larger zip file:

I know there are some glitches in it still but if you have any suggestions or comment please post them up here. Thanks.
