That is a very impressive game, I have no idea how you managed to implement that many features and art as a solo dev, great work!
I enjoyed the gameplay, the slow down was a nice touch and the levels were well made. They didn't feel repetitive and became increasingly difficult and interesting.
I would suggest adding some air control after looping, to reposition Loop-man when doing successive loops.
As a side note, we also made a game featuring Loop-man! It is pretty cool to see the "Loop-man extended universe" come together during this game jam 😁
