Stunning art and cozy vibes, my highlight is the intro sequence, giving Studio Ghibli vibes. The music is great, and the main menu has a level of quality I'd expect only of a fully released game.
My only complaint is that controls felt a little unintuitive, and it seems to be more of an exploration game / flight sim than a rythm game. This is crazy good for 1 week and 3 people, be proud!
