As others have said, the game doesn't really fit the theme in its current state but I would be interested to see the version you set out to make.
Other than that, this is a decently made skeefree-like. The tutorial is perfect and this is only the second game from the jam who's music I've been happy to just let loop as I type the review.
As a gut reaction I would definitely have preferred fewer objects generating and the pickups to not stop you but then I guess that would just be skeefree - maybe it wants to be more like a cross-country ski game and the obstacles help keep the player slow; you could spend time moving left/right, taking cable cars back up, and using an overview map to find nice clearings to get the most velocity down...
Anyway, before I start designing a whole different game, great job and nice work submitting something!
