I'd say the game needs lower settings or some optimization, because even capping it at 30fps it lags and my device heats up. Also i've found a glitch where intstead of spawning at the race, the car spawns at a random place and the countdown becomes an endles repetition of the number 3 until i quit. Besides that, great game, even tho i liked the unlocking tree from the beta better, it gave it much more sense to explore the building possibilites.
