Pretty fun
This is a pretty awesome game, great concept and not so difficult that you rage all the time.
Pretty much just the one problem though: collision detection.
Its nice to go under a block and be able to 'K' my way out (even if it feels a little like cheating :D) but when I'm standing in a place I know the block isn't going to hit and then it doesn't and I die anyway its just a *little* annoying. :P
But aside from that a pretty entertaining way to waste my time. :D
