Cool twist on a Pac-Man style game! I would suggest making the collider for the player a little smaller. It would get briefly 'hung' as it passes corners and it was hard to get in the center tunnels. Maybe also a way to spin the stage faster? A lot of the time I would try to turn the stage, but the player character had too much momentum and ended up rolling into a ghost before I could get them to move in the direction I wanted.
Nice job on your submission! A simple but fun concept! I could see it being a fun mobile game, too. I also liked the touch of the dot collect sounds increasing in pitch when you collect them in quick succession.
