4 stars: It would be nice if you didn't have to reset the engine and turbo levels back to one after every level, ESPECIALLY after purchasing a vehicle. You lose one star for this. Otherwise a fun and funny game with pretty good graphics.
3 stars: Fun with ads. Unless you're willing to pay with every round you have to watch a commercial and if you need to top up you're going to watch more commercials. You spend more time watching commercials and you do actually playing.
3 stars: Wow, that's a *lot* of ads. Game play is predictable, just keep upgrading until you reach the goal. Upgrades get expensive quite fast, and it seems each new vehicle starts at the last price paid for upgrades. One has to watch ads just to get enough $ for the upgrades, don't earn enough otherwise. Graphics are pretty good. Just unlocked 'steering' so will see if it gets any better.
2 stars: Good quality, and added stearing was enjoyable, but not the bombardment of ads. Collect millions of points just to get an inch ahead. I wanted the ship scene, but i think they deleted it from the game, since the same levels started repeating
