Icycle: On Thin Ice is a platformer that sees you put on the hat of naked cycling hero Dennis, who is chasing the woman of his dreams across treacherous, snow-covered terrain. Your job is to help Dennis find love by making your way through the game's levels by peddling down slopes, jumping through moving platforms, and much more.
The folks at Chillingo were showing off Icycle 2 at GDC 2013, and it broke my brain just a little. The game mechanics themselves are very simple; the controls are ultimately the most basic ones you could have for a platformer game. The real trip is in the art style and storyline.
