This was fun! I almost got frustrated and quit early, but then I discovered the floating platforms and made it to level 3. I wasn't very motivated to replay it though, because I didn't want to repeat the first part again.
This is really great! First time all the ships crashed, but second time I got 5 to survive. If you want to develop it farther, I think it would help to have some easier levels and gradually ramp up the difficulty
Love this game! Very satisfying to learn the songs and the sound design is beautiful. I did get stuck though and couldn't figure out the puzzle after unlocking all the notes. I'm probably missing something, also not very good at puzzle games :P
This was really fun! Maybe default the volume at 50% since it was a bit loud. Also it would be helpful to show some kind of tooltip when you switch to the cat on the surface to indicate that you need to press space to interact - took me a while to figure that out.
