Some of the background is a bit fuzzy looking, probably scaled too much, but apart form that the visuals are very good. The concept is very nice, a cool idea. The bad thing- controls are mushy and there are blind jumps where you can't see where to go. 

Gameplay video:

I really like the graphics and animations, so nothing wrong with that apart from maybe the resolution of the background being too small in some cases, as for gameplay I think the controls could have been a little better as I didn't like how stationary it felt to be the cloud, some left and right movement was probably needed, I think the ice block is a good idea but a little too slow for my liking. Also it should be easier to tell which parts of the background are solid. Overall good game for the jam, fits the theme really nicely and looks great with flow-y animations :).
