Thanks!
I definetly want to fix a bit the camera, maybe making it follow the player more slowly, and a bit offset to be able to see more of what's in front of you. I was almost going to put a "kinda" on the "Got it" button on the tutorial, because I knew people wouldn't really understand until they played it, I might just ditch the whole tutorial out and instead just make tutorial levels (even if the 1st is enough). I don't quite know with that momentum thing where the shape goes flying up and spining, but I'll see what I can do. And I'd really like to make it for mobile.
As for the music, you could try and solve the easter egg ;) (clues in the description)
