Hey sorry, would you mind explaining what about the movement felt sloppy or hard to control? The game is designed so that the platforms remove all precise platforming, or at least that was the intention, so I'm not sure where I may have messed up to make you feel that way.
No there isn't any music, I have no sound experience and did this all myself learning as I went. So I ran out of time and had to plug what free assets I could find.
