Icy Tower Classic - Macintosh/iOS/Android title
The main game mechanic is that the faster Harold runs, the higher he can jump. This can be used to pick up speed in order to jump several stories in one go, something which is required to string together combination jumps which in turn score the most point. This is made harder by the fact that the screen where the player is seen is constantly moved upwards, faster and faster, and the player must keep up or forfeit the game.
Controls are very simple with only left, right and jump being used. Replays can be recorded and shared with friends and via a global online highscore function. The game also supports custom characters which either can be created by the user or downloaded from the net.
