Fun but inflated

This game is fun, but the prices are way too inflated for current methods of obtaining resources. Either lower the prices or raised the amount given to you in a race or as a reward. Also, I just spent so much in game cash on leveling up my drone, and when its time now to get star 2, I have to pay either for another drone of te same type or 100 gems

*edit to 1 star*
Do not spend irl cash on ANYTHIG in this app. I spent cash on 75 gems and topped the leaderboards with 42k high score. 3 days later, Im second , a day later Im third . By now, Im kicked out to fourth place by bots meant to keep revenue flowing and the leaderboards not. Reall devs? Make it so the leaderboards are fair and maybe you can have a few more stars.
