I'm surprised that no one voted for your game yet. It was a lovely short experience! Very clean pixel art and presentation is really great. I got stuck on the part where you align the dots. I'm not quite sure how the puzzle is solved but I'm assuming it has something to with Ursa Minor? I think you should at least give a brief tutorial. Some more minor feedback:
- Increase the dot size and make it a color that contrasts so it's easier to see
- Allow the player to rotate in any direction
- Highlight which part of the piece moves when the player hovers over (I accidentally misclicked many times)
Btw, the music box melody is peaceful and well made! Good job on the game!
