Had a lot of fun with this entry! The boss fight specifically was a nice little bullet hell and the mechanic of capturing enemies was very unique. I had a little trouble actually pulling off the circling around enemies on a keyboard before the string resets, but by the end it was getting more manageable. The art is very nice! I also really like how well the little notes fill in the story with so few lines.
My one issue was with the fact that the camera scrolls with the player vertically on the platforming sections, I found myself floating above stuff I couldn't see more than I would like.
Overall though, great job!
