Very well polished game. Nice work! It took me so long to figure out the mechanics. Level 3 was quite a difficulty curve for me! I didn't even notice the instructions were on screen for like 5 attempts.
The artwork is very pretty, I like how bouncy he looks. The game overall has a lot of merit, you could definitely put it on steam.
If I had to make one suggestion, I'd have liked to use the number keys rather than pressing space and hoping for the right combination. It felt a bit arbitrary.
