A few hours of playing and I left the game on overnight. I also did use an autoclicker for some of the running as it was starting to hurt my hand. So I would say over a day's worth of playing. I think it's well paced as is.
Nice! I'm finishing the races tiers, and I've fixed the clicking to sprint, actually 1 click is 1 step, when on keyboard you need L+R to get 1 step, so clicking was duplicating the steps. Thankyou very much for your feedback! This help me a lot!! /bow
