I really liked the idea behind this game. It was cool trying to lure the zombies onto the treadmills. I do wish it was zoomed in a little more, or had fullscreen enabled, but it was still playable. I am a little sad you didnt make another title or upload a title image though, I think it would help atract more people to play the game. Your marketing isnt doing your game justice :) It is a fun game, you did a great job!
Hear are my title ideas: Attack of the Untread, Dreadmill, Zombie Workout.
