Heaven and Hell Tetris are two different flash games based on two different xkcd comics. Know what else they are? Two different games you can play below.
I liked Portal tetris better ;-)
Those damned audio ads! >.< Scared the shit out of me lol
I personally just find them annoying, but they’re outside of Steve’s control.
Is it bad that the first thing I did was try to figure out how to lose at Heaven?
