this is a solid game, I like the whole space and winter style and I have some feedback: a game like this needs too have good level design and my problem with some of the levels is that they are just too hard especially for a game jam game BUT level 3 is the best, its probably the easiest level and is used to introduce you to a new mechanic: jump pads (they are super cute btw) but then they are never used again ): why are they never used again? they add an interesting layer to the platforming and make the game more enjoyable. apart from that this is a good entry, well done (:
sorry if I was too critical
also if you jump before entering the next section of a level you can avoid the bug where you get stuck
