The game could be fun if not for some very annoying issues. First, the people complaining about too many ads are correct. You must sit through an add before the round and again at the end. So there are a minimum of two ads just to do anything. If you upgrade or change, you will have to watch another ad. I understand the need for ads to pay the developers, but this is excessive. Second, and a much bigger and annoying problem is that when you are done watching ads and ready to play, the game lags and you have to wait an excessive time before it will let you launch the bike. Sometimes you get impatient and frustrated trying to pull back the sling and it won’t move, then suddenly without warning, it moves. This results in a miss fire on the launch, and even sometimes send your bike backwards instead of down the track. Very bad glitch and should be corrected. Seriously considering deleting this game due to pure frustration.
