The level design in this is great! Having everything work out was very satisfying.
Music and art were great.
As far as controls go, the only thing that annoyed me was that you cant change direction just by pressing another button, you have to let go of the button you were pressing before. This isnt really a problem, but it feels weird to me because all the games I remember playing with this type of ice sliding mechanic(mainly pokemon) weren't that way, so my muscle memory kinda got in the way.
Besides that and the sfx being a bit too loud compared to the (great)music, I had a lot of fun!
Good job!
