Personally, I wouldn't base the whole game around ice controls because of the frustration Yomic mentioned. But for what it I found it executed well, the controls make sense for ice levels. The music and sound effects fit the theme well too.
However, I couldn't get too far, not because of the frustration, but because the game seemed to hang occasionally. Cannot pinpoint the cause. When it did hang, closing the window wasn't enough as the music kept playing. I'm on Windows 8.1.
Aside from the crashes, single blocks are the devil, more so when there's a single block gap you have to jump through right above it.
