I enjoyed it very much, you packed a good variety of mechanics into it that all work very well together! Riding on a long track of ice feels so cool - pun intended! Having the sunlight approach only when you move makes it a strategy game, not a reaction based one, which is in my favour.
The sound effects are rather simple and abstract, though IMO they fit the game's style and theme. Some catchy music is all that's missing.
There's one thing I don't get: what's that yellow line in the middle of the screen? Sorry if it's explained in the game's description, I didn't read it all.
(I also like it because it reminds me of my first ever game jam game. :D)
