I guess I didn't have the patience to get all the way to the end. Eventually I tried to let the hero kill me but it seemed like I had infinite health so I kind of gave up. Definitely wasn't meant as a criticism though, so maybe I would amend my statement to say that I wish the end came sooner.
I thought originally that it was one of those infinite procedurally generated running games like Jetpack Joyride, so I think that's what I was expecting.
