Being a mobile port, its a very simple concept and it is as expected interface and graphics wise. The idea behimd this game is that you click on tiles to turn the track so your rally doesn't hit a dead end and crash, instead keep the car going along until a finish line tile eventually appears. The problem however is that while you have the typical straights, curves and four way junctions, there are tiles that split in mutliple directions, for example one where you approach and can go left, right or straight and one where you go left or right. You have no control over which way the driver will go at these tiles. None. He will randomly go left or right or straight on a whim without any indication from the game as to why that direction was chosen. He'll frequently follow to the left and instantly crash rather than follow and complete path you made to the right. Without the co-driver bonus, you don't even know which way he will go until he actually does it.
The only control, the only gameplay element there is in this tiny, single concept game doesn't even work, leaving the game with nothing of value. How did the developer not notice this? Its the only thing in the game for christs sake and its bust. And if they did notice that a left/right/middle button is needed then they didn't even bother to do something. The developers should be ashamed of this game. More unnecasary crap on steam. More unnecasary crap on mobile.
