Have to agree. Recently downloaded another tunnel runner/survival game because it had enemies/shooting involved as well. It sucked. This runs circles around any other game in the genre. Would be interesting to see what you could do in a follow-up if you were to add combat into the mix.
One of the few "How far" games I still play a lot, even though I absolutely stink at it. Even bought it on my Android phone as well after having bought it for my iPod.
