Icy tower is a freeware game originally released in 2001. The main objective of Icy Tower is to keep climbing the tower and not fall. The screen progressively moves up faster. Players can also pull off combos by jumping more then one step at a time.
By default, players use the space bar to jump and the left and right arrow keys to move along platforms.
As new versions were released and the community started to grow, the developers added new functions.
The game has several mobile versions including an iPhone version.
