I love the music and the art! The character's animation is adorable. I also think the idea of having the physics randomized is a super creative use of the limitation and really makes the runs interesting. Also, correct me if I'm wrong, but the levels switch between 'grass' and 'ice' depending on the amount of friction right? If so, wonderful touch that makes the randomized physics a little less annoying, such as to not make the player unexpectedly go careening off a cliff (which I did anyways :P)
All around great entry!
