Really nice style, fun mechanic and wonderful relaxing vibe.
I suppose my only feedback (and I guess this might just be my taste, not a criticism); maybe the 'dangerous levels' (with the spikes) could have come in a little earlier. I felt much more invested after those started appearing. Once each movement had a sense of risk and importance.
You managed to get in quite a fair bit of content for a jam game. Impressive!
Overall really fun! Well done!
