What an unusual design with a great concept! I like how your deaths helps you to beat the level, though the death quotes makes me feel bad for them, gives uncanny vibes. The retro style is lovely, I especially liked the sound effects and how the player 'dances' along the music. Was that intentional?
The puzzles were clever, though not too hard. I think giving 60 moves to the player in the final level is a bit overkill.
Loved it!
