IceClimb is a vertical scrolling platform/puzzle game for TI graphing calculators. You control a penguin trying to reach the door at the top of all 5 levels. You will have to jump on blocks, climb ladders, and think hard before each jump. You will even have to play with Spikes! This game features sound if you hold the calculator up to an AM radio on a dead station, or you can get clearer sound by plugging in a 2.5<->3.5 mm headphone converter.
This game has a history in TI-Basic as a game with fast scrolling using strings, but the game has since been rewritten in assembly language.
