Would have given 5 stars, but some levels and keys are impossible to obtain!! I very much doubt, anyone has obtained all the keys, including the developers! And the cost of cars is ridiculous, especially compared to what you can earn! They have added way more ads and after failing a level, they took away the option for main menu, your only choice now is restart!! Doesn't matter if the level has already been completed! Very Annoying!!

Too many ads. I just want to play the levels. I open the game and hit play to get into a level and boom hit with an ad. I messed up and wasn't to restart the level boom ad. then I finish my 35 second level all to get another ad. if I want to upgrade my car? ad. I'm uninstalling because of this. it's just too much. I spend more time in ads than the actual game.

This is actually very fun game to play, and I've gotten quite a ways through it. Not too difficult, but definitely has some challenges, and hunting around for the hidden keys after completing the level is like a whole second adventure. I think there are a couple errors in the game though, where a level will not have as many coins as it expects you to find? One example is level 208, which claims to have 58 coins, but I only find 29 doing the whole track. Thoughts?
