The concept and gameplay is simple but fun and challenging. And i think THIS is how a mobile games should be. Simple and fun just enough to fill a brief free time. The game is entertaining with many events to compete in, interesting plot, cool artworks, wonderful visuals and breathtaking sceneries, and there are a line of amazing cars with extremely outstanding visual details plus many customization and tuning options. you can even interact with the car as if it's in front of you! That's amazing
