Love the art, it's so cute. The ending was sweet too, I like the writing.
The puzzles are interesting, but the wonky physics did keep me from enjoying the gameplay fully. I felt like the 10 second timer made it a bit too hard, but that could be because of the physics too. The biggest problem was the spike hitbox for me.
But other than this, it's a really enjoyable little puzzle game with really good visuals and catchy BGM!
