I tried your game (just the lite one) on my new Samsung Captivate, and it is pretty cool! Very challenging tho

I'll probably buy the full version if I can manage to beat the demo.
One issue I've noticed is it seems if I exit the app (By pressing home) and go back to it; if I am on the level select screen then the level thumbnail goes black; if I was in a level the whole screen is black.
Also, you should make it possible to play it non-fullscreen. I'd like to be able to respond to txts and stuff when I'm playing.
