Balloon in a Wasteland Addicting beyond belief.
This is an amazing game. My first playthrough I thought it to be impossible but I've actually scored daily 18th under the name Nyaar. I'm still trying to figure out how it's been beaten in under 20:00:00, but if I can get this far (22:45:59) guess others are capable of better.
Great game. (Oh and props for making the shotgun the worst weapon there. ;P)
