Very fun and rewarding! I felt really clever with each puzzle I solved! The music, sound and visual flavor of the game was really fantastic as well. The fact that even the enemies have a special animation when they slide on the slippery surfaces was such a cool touch!
I think one the tiny bit of feedback I'd give is that I wish there was more attention drawn to the randomness of choosing which effect would happen next. I didn't realize it was random until about 12 levels in. Honestly I think the game would have been better without the randomness at all, but I guess we have a theme to conform to ;)
