Good Jam, my friend! I liked the ice movement, although very hard to control, which I'm sure is the point. The small detail of adding time goals made it that much more enjoyable. It wasn't just about beating the level anymore, but about trying to get a certain time. I admit, I restarted some levels to try and get the best time :)
The last level was especially hard. It feels as if there are weird push forces that try to guide you throughout the level, but end up pushing you off sometimes.
Overall, Fun Game, and enjoyable mechanics!
