This is a fun game, that is if one can overlook the large bouncing yellow smiley (and other such happy faces at the top of the screen). Moving the vehicles around the play field and "missing" the granny and her walker IS challenging; but it can be done. I enjoy using this app when I have down time, as it constantly changes! It is very interactive and allows the player to change the vehicle types to many different sets. The scene of the parking lot can be changed at whim as well! Love it!!!!! I really like this game. The basic game is very simple with much harder challenge levels that you can opt to play as you reach certain milestones. You can build buildings with the coins you earn, which is kinda random, but still enjoyable. I watch ads when I want more perks. If I didn't want perks, I think that I would rarely see an ad. I appreciate not having an ad forced on me every 10 seconds like some other games. The devs of this game have done a wonderful job of not forcing too many ads and utilizing them sparsely after so many levels (able to be skipped after a short timer) Truly perfect balance of gameplay and ads. The gameplay is easy at first, but there are challenges that increase in difficulty. Great game, I could play for hours!
