I like the game concept and the characters are cute. Puzzles are a bit too simple. The hit-boxes are a bit annoying, and controls feel a bit stiff. Some physics based movement with acceleration, sliding and bouncing would give it a nicer feel.

This was a good attempt, but I feel you may have over scoped for this jam. Next time focus on one level and add sound effects to it. Maybe some music too, gives more life to the game. One more thing, lookout for different collisions and how they affect the gameplay. Level 3 the platform pushed me off the floating thing and I had to rush and jump back on in time.
