The game has a handful of bugs, some of which break the game and force you to restart the app. Besides that, it's a good time waster. EDIT: After playing for a few days, the amount of bugs that require you to close and reopen the game have grown far too much. I'll just randomly get a pop-up asking if I want to watch an ad for a boost. However nothing in the pop up works, so you just need to randomly close the game if you want to continue.

Honestly a great game worthy of 5 stars, BUT the developer is so money hungry, he places constant ads after EVERY "challenge" and expects the people who don't want to see ads to spend $10 a month. That is absurd for a mobile game. I understand ads on a free game, but space them out atleast, I feel like 60% of my time is ads. Also, the challenges are too easy, I am going extremely under leveled, and still beating them. You can't even play this game offline either, so no airplane fun.

it's a fun time killer. but I only give it 2 stars because in the daily competitions, your vehicle can become "trapped" underneath other vehicles, which will cause you to lose the daily bonus, and the race. I just now spent 15 seconds, glitched, underneath a vehicle, that cost me a win, that I would've won.
