The update doesnt always play the ad videos. And why show the upgrades with bars to level 12 and then not have any way up buying upgrades to get to level 12. I am at Level 10 on all upgrades. And tree should be a fixed item on one side of the screen or the other. Having it only at the track level with all the camera views makes it hard to cut a good light when you want to see the race from afar...
Overall, good game, just needs to modify those few little things.
Ehh, soso about Dragster Mayhem - Top Fuel Sim
