OH YAY!
Spelunky reached 1.0!
For the unfamiliar, it's a cave divin', animal whippin', rope climbin', damsel savin' good time with procedurally generated levels - so it's different every time you play it. Supports gamepads too.
Spelunky v1.0!
You will die a lot but on different levels every time!
Play it before Xbox Live pretends it's new!
