Very good game, very fun and with a super cute artstyle! :D
The puzzles were interesting, the mechanics simple but well studied, overall a pretty solid puzzle game!
The only critique I may have is the movement is a bit clunky, as having to press for every move is a bit tedious when having to do backtracking.
I also really liked the tiny esthetic features, like being able to change the character or the color of the level! Small things that some would deem useless, but I think they make the game lots more fun and cute!
