Really cool puzzle game!! It feels very well paced, with new mechanics introduced at just the right times to keep me engaged. The little dancing purple creatures are so funny to me, and I love them, so I was sad that I had to kill them, but oh well. There were some really creative puzzles, and clever solutions. The theme implementation is quite cool, giving this type of puzzle game a new feel while still honoring the genres core features.
My one critique would be the pushable boxes not showing up until the 3rd floor of the level, so I had to just kind of assume what they did, and hope that when I got to it, my work would not be wasted. I think an introduction of pushable boxes that was similar to the stabby boxes (1st floor, low commitment) would've been nice. This didn't reduce my enjoyment at all, just something to note I guess.
Music is nice, visuals are stylish, being simple but clear, and all around the game is just a fun time. Well done!!
