I think most of the drag you see comes from collisions, if there were no walls it would take a while to slow down. originally I had it without any drag/friction, but I found it got a little hard to control for new players. I tried to strike a balance, and right now, a skilled player could get a much better time by not having any collisions, but it definetaly needs some tweaking. for V2 I'd consider adding different levels of drag/friction per course maybe. Thanks for the feedback!
