Pretty cool, actually. I'm not overly excited about runners, but the loot aspect of this game definitely adds an extra layer of "fun-ness." Finding different weapons and armor in treasure chests is always fun.
My only beef with this is that they went the temple run route, rather than subway surfers, for handling lanes. The whole tilt-to-move mechanic was neat when it was new, but I've really grown tired of it. Plus, I play on an iPad, which just makes it that much more loathsome.
But the tilt thing is simply a personal preference on my part. This is a good runner and more compelling to play than a lot of others out there, due to the loot aspect. If you even remotely like runners, it's definitely worh a go.
