4 stars: Around lvl 30 it begins to really take a long time to get enough money, the progress really slows down. It's a fun game. I played it about 15 hours and got to lvl 45. I think what make the progress slow down is the fact that you need screws to upgrade, which are slow to gather. The circuit was fun but too short. I would play more if there was no screws. I have watched over 200 ads. Didn't spend any money.
4 stars: I reached level 119..when will you release further updates...please update necessary things in the game.I need to unlock new cars...my money also reached 1billion... After 30days I did not received any daily rewards ...fix this... Upgrading cost is too high... I brought many cars by unlocking new levels,but all cars are in just 1St level....fix this also
3 stars: I like the game but I wish there was a way to upgrade the speed at which the cars come into the warehouse, or even control when the shop opens up. When the shop closes, it's pointless unless no customers show up. Good game still, a lot of potential
2 stars: The game concept is cool. BUT....the coding is patchy. The little boy only gives you parts once. Characters get stuck, you don't always get your prizes, the game doesn't function smoothly, and you spend more time watching ads then anything. A lot of items cost diamonds that take forever to earn. You pay for upgrades in speed, but nothing happens. If the game was fixed, and improved it would be fun.
2 stars: OK game but they just ...
