Lovely concept with being an ice cube that dies if it melts. That's a beautiful way to convey a health bar without one.
Needs a bunch of balancing and testing in order for the levels and puzzles to be fun. Levels 8 to the final level were annoyingly tedious to clear because there was no indication on how large the ice blocks and balls needed to be to progress through the level. I had to guess, and even though I had "cleared" the puzzle the mechanics made them really hard to execute.
Still I think you did a good job by sticking to the theme by having objects in your game scale according to environmental factors. Especially the blue and red zones.
I enjoyed design of the ice cube's face. Very cool!
