Speed is fun, what could be more fun, more speed. Adding some kind of acceleration and/or bunny hopping mechanic would be fun. The music was nice. And I think you broke the "cycle" you mentioned, yes it's a simple game but a complete game!
Thank you for playing! I did play a bit with acceleration but it felt more like ice skating then running, so I removed it. Mby some speed ramps would be nice tho.
