Edited my 5 star review to a 1 due to the introduction of invasive ads after losing. Used to be that you only get ads by choice for shuffling shop cards and to continue after losing. Now, you get an ad after losing even if you choose not to watch one to continue, plus you don't get to continue the lost game after that ad, which is incredibly frustrating. At least push the invasive ad and let us continue the lost game.

The ads after every few race even when you don't try to continue your run absolutely ruin it. You get used to tapping past the post game screen, then start to tap to start you bike and quite often you end up clicking on an add. Very obnoxious and ruins an otherwise incredible game. I was having a lot of fun with this one before the ad problem started.

It's an ok game. The art work is entraining. The controls or lack of controlling the bikes is a bit annoying but I guess that's part of the style. It's fun and a bit addicting but just ok over all.

Game has been ruined by invasive ads. What was wrong with your old model? Now instead of watching ads for shuffles, I just won't play your game...great job.

The game seems great but the fps is just to low. It seems like I get only 20 fps on my LG V20, which is something I might expect on a highly demanding 3D game but not a 2D game.

Game is excellent. Great concepts, and a generous reward system gives easy access to both the paid currency and the in-game currency, allowing you to upgrade riders, bikes, and guns. That part is great. However, a few things hamper the execution. First, Google Play integration is broken for me. I can't get it to sign in or track progress, meaning that when I switched phones a couple weeks ago, I had to start from ground zero and lose out on my upgrades. Frustrating. Similarly, they ad-based system for "shuffling" upgrade cards doesn't work. You hit the button, the app stutters but usually loads and plays a 30-second ad, but then the app crashes and reloads to the loading splash screen. Again, frustrating, especially after you as the player just viewed an ad. Nothing happens, the cards do not shuffle. Immensely frustrating and unfair when you just used data and time to earn the game ad revenue without receiving the promised in-game reward. All that said, however, the game has no other ads, no energy system, and the IAPs present a good value but aren't necessary to progress through the game. Very cool game, and with a little polish to smooth out the aforementioned bugs, it's easily 5 stars.
