It's a fun game. I even bought the ad free version, but I find myself irritated by how easy it is to die, even if you land perfectly. Or if you try and go upwards, it will flip without you wanting to even on flat ground. Also, purchasing a revive with gems only seems to be available offline, which sucks because I've bought all the bikes available. The only thing the gems are good for would be buying revives but usually I have to watch an ad to revive, even though I thought I went ad free.
