I stumble across this a while ago :

Walaber got his fame for a ragdoll physics trampoline game. It was hard as shit to master, but overall crazy fun. Still no word of a ski game, but as you can see, the engine exists.

I believe it is our right to band together as as a collective and bug the crap out of walaber until a game like this is produced.
