I really like the concept and the music.
Took me some time to find the short cut with the levaitation upgrade and there for died a few times to often in acid. ๐ ๐
I also managed to break the game some how, after the power upgrade, when died and put back into the cage, I immediately pushed the standard attack, the cage broke and the game with it. And sometimes I had to push levitation twice, to get it started, not sure why that happend. Just in case you want to investigate.
Overall:
A fun game.
