The visuals look nice. Cool that you took the time to create some animations.
I think you also fulfilled the theme really good.
One thing: the audio, especially the jump-sound is really annoying over time, since it is a thing you do very very often.
Besides from that: nice puzzle, nice graphics, Theme fulfilled really good. Solid entry! I also like the story. I want to see this icecube having a minigame-cameo in another game where some character just makes a drink :D
