Very fun game! I can see myself investing hours into it. The art is beautiful, the characters are cool, and the mechanics are really fun. As it is, I think the game is perfect—but I can also see potential in adding time attack trials or "limited moves" challenges. The latter could even be implemented as an in-game mechanic in certain areas to add a bit of extra challenge—similar to the moving poles that require quick inputs from the player. I think it would be fun to have poles that disappear and only reset after failure or a restart.
Overall, I believe this game has the potential to be huge. The only missing piece is a great soundtrack—add that in, and you’ve got the key to success!
