Ski Stunt Simulator

You control a 2D skier performing various tricks on the slopes. Where Ski Stunt Simulator stands apart from other physics is the fidelity of that control. This isn’t a simple ragdoll game–far from it. In fact, Ski Stunt Simulator is the result of collaboration between a programmer at Relic Entertainment and a researcher at the University of British Columbia, and the robust simulation definitely demonstrates an academic level of engineering.

The game features 14 levels. The skills and tricks required to pass each level vary. One level will require you perform a backflip on a certain jump, another will require clearing a stack of crates, and another will be to simply make it to the bottom of the hill–dead or alive.
