Really clever puzzle game!
This reminds me somewhat of the game Baba Is You. Not necessarily in mechanics but in the overall presentation of the game and puzzles, which is really well done. Also much like Baba Is You, this game totally fried my brain.
I was stumped after a few levels, and it took me a little while to understand how the game worked at first. However, each time I solved a puzzle I felt like the answer was sensible and the puzzle was cleverly constructed, which I feel is very important for any puzzle game.
Also visually speaking, I liked the sprites for the different puzzle elements and the player. The designs were simple but distinct. I also liked the music and sound effects used. They fit the tone nicely without being too repetitive.
Really well done!
