Ok, gave this a try. Can't find any IAP, but I might be missing them. There are small banner ads that disappear during gameplay
As for the game itself, you can tell it was made by devs of Parking Simulator, and I mean that in a good way. While another post here said it looked slow, I think that's good. The game adds some more realistic, more precise handling into the obstacle course evasion. It's certainly no fast-paced Trials, but it's fun in a different way. The touch controls are pretty good, although I find swiping to activate the boost power-up a bit unresponsive. The obstacles are varied and fun to avoid, and gives the game more of puzzle platformer vibe.
