I found the rotation a little disorienting where I think my brain expected it to change direction with along with the player. I think a run button would be good too (some of those walks around the loop take a while)
Thanks a lot for playing our game and the nice feedback! :D I agree that the long waiting time when you make a mistake is a bit of a flaw in the game. A run button might indeed help, although we would have to redesign some levels to take that into account
