I didn't play this game on the Feedback Quest jam but I'm glad I tried it this time. It's not exactly my kind of game but I have to admit it's super cute and has a warm and relaxing atmosphere.
I managed to finish all the levels. I agree with GamePasta that it feel a bit too much like a tutorial with new mechanics introduced too often. I feel like you already have enough mechanics and variety to triple the number of levels. If you make new characters / mechanics, they should probably only appear much further down the line.
Great work, especially on the art style :)
