is a brilliant remake of Nintendo's Ice Climber with updated graphics and level designs. When your character jumps, she will automatically attempt to destroy any blocks above her head and hence creating holes in the ceiling for her to advance upwards.
Press the Z key to hit sideways, and use the X key to jump. Cutscenes can be skipped, and the demo features a boss battle as well. A definite recommendation for fans of the classic. Scroll all the way down and click on the Win32 link below the red button to download the trial version.
