N(ice) game! I like a snappy momentum platformer, and the ice theme is a great fit. Not sure what I thought about some sections of the levels, like the zig-zag drop-down on the first level, or it's ending with the 2-high obstacle right before the finish (is there a way to clear it with one jump? Doing it with two seems difficult without slowing down). Even with a few attempts at some of them I'm not sure there was an intended fast/smooth route - admittedly a bit subjective, but my preference is maps/levels with designed flowy routes.
The tricks make a good addition to the mechanics, they were fun. Well done :)
