The basic idea is great. I love this kind of game. However, the execution is greatly lacking. Im just not ever going to pay much into any game, so waiting around for gas in the tank is the first turn off, but are understandable to some degree. However, waiting periods get longer and longer. Interaction also feels like its all rigged, and the way the views turn, sometimes prevent you from seeing where you need to go. The upgrades are required to advance and run different courses, but dont feel like they really make much difference on handling. Im also being plagued with the app crashing every time I close an ad. Overall, I just want a game that I can play to let off some steam occasionally, and this doesnt do it.
