Its 9.5/10 for fun! Everything can be made better, heres a few suggestions: 1) only compete against 1 tier higher or lower. 2) show top 4 at end of races 3) give more points if a lower ccd car beats a higher ccd car 4) get rid of that button to use "5" gems to re-enter a race early...Ive wasted too many gems by accidentally pressing it. 5) have faq on the app. I dont understand some things example: what does cc mean? Are there any robots playing or is everybody real? 6) show where ppl are playing from (for real, not just a flag they chose) 7) thats it...for now...
