Thanks for the feedback. I'm glad you liked at least some things. I wanted the game to start out easier, so I also chose the lowest level with actual snow as the default during the opening scene. I wonder whether I should have increased that, though, since the storm actually makes the game much funnier to play.
You're right about the acorns.. I barely fit the game into the time period of the jam, even finishing a fix to the web version literally the minute it was due, so I only got the Windows version entered. I'll also take the jump speed into consideration.
