This game is awesome. I have had it downloaded for a while and I always find myself going back. The ads are not to frequent like most games which is a major plus. Its simple and fun. I gave it 4 stars because of one issue that is getting very frustrating. When the track fits together they often times create a bump that makes the bike flip with no way to really save it. I assume it's a bug so devs please fix that issue and it'd be an easy 5 stars.
