Really nice idea! Level 2 took me a while to figure out but i got there in the end. Level 3 i couldn't finish cause i kept getting stuck in the mirrors and flew out of the level a couple times as well, but i think i know how to beat it. I had to give up on the 10th time i got stuck. Needs some more polish but the idea was really fun! I enjoyed it :)
Edit: Oh and the gravity felt a little weird as well. Don't know if it was by design cause space and all
