I agree, loved the idea, but the theme requirement was met by the one arm concept, a couple more buttons for turning around and aiming would have been appreciated. I enjoyed it while it lasted though. and gave it high marks in everything but design.
I appreciate you all playing it and commenting. We really wanted to make one button work, for the challenge of it, and I don't think we'll be patching in other buttons. That said, if we build a more fleshed out game on this concept I think we'll be using more buttons and/or cursor control for aiming. Legit.
