It's not as toxic ad other games here but it's near. At level five train I realized that my "playing" the game means holding the phone and watching ads. Really bad balanced gameplay. I can understand that it's needed so the player has to watch ads but still after many courses I had 7k. One not so careful course and I'm back at 4k. Nice to try it but pain to continue. One additional star for the proof of concept and nothing more.
