The concept is really cool, I think it has potential!

I really liked the concept. This would be a cool one to see fleshed out and polished a bit more! 

It was a little bit hard to understand controls at first,  but overall the game is very good!
I like your interpretation of the idea!

Very nice concept, having energy sources to protect yourself. I had a little trouble finding the controls, but than it was very interesting to see the energy angle in this kind of game!

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.
