Really fun game! Easy to start playing but not trivial to be beat. I especially liked that the levels were designed so that the next platform to jump to was not always an obvious choice, but there was also route planning involved.
Controls were responsive and the game clearly fits the theme. Graphics were nice and snow effect really added to the atmosphere. Maybe adding some music / sound effects with help building the atmosphere even further.
One thing I feel I have to mention, even though it's just a really minor thing: in the menu, it is not clear which button is the selected, I accidentally quit the game the first time (and later again when trying the game second time). Luckily, there's no important other buttons to press than play, so if players just press enter without trying to control the menu, the game starts, so this probably hasn't been a problem with many.
By the way, how many levels there are? I didn't manage to beat it.
