The Blocks Cometh

The Blocks Cometh is one of those "reach as far as possible" kinda games. It has that same "one more time" feel to it as Canabalt. In The Blocks Cometh you're thrown into a Tetris type of game where your character need to climb up on top of fallen blocks that stack on top of each other. The goal is to reach as high as possible before getting smashed by a falling block. In case you get caught or a stack of blocks is too high you're also equipped with a gun so you can shoot blocks.
