I felt kinda mislead by the trailer for this one. While everything on the surface claims it's this big musical puzzle game the actual puzzles are purely mathematical in nature. The music is just a theme and all of the puzzles involve figuring out how many notes up or down from a given note you need to be. It actually allows you to just swap the letters for numbers.

They're going for a very cute and child friendly vibe in the story, the environment has a miniature diorama feel, and the puzzles themselves are fine if you enjoy the same logic repeated to exhaustion.

Might have been more fun if I went in with the right expectations but even then the repetition of the same puzzle with different iterations felt tired by the time I reached the end of the first area.
