Icy Tower

Icy Tower is a freeware computer game by Swedish game developer Free Lunch Design. It is a platform game set in a tower, where the player's goal is to jump from one "floor" to the next and go as high as possible without falling and plunging off the screen. The higher the player's character climbs, the faster the tower's floors move downward and the harder the game becomes. By default, the player controls the character using a keyboard.
