Loved the game. Flat design for flat earth was the best idea I have seen in recent times. By the looks of a vertical screen I believe you have already considered releasing a mobile version. If you add some power ups and a progressive difficulty this game can go places. Loved the blood effect both splatters and after hero's death on the machine as well. The game was a treat to play and graphics and music helped it in a good way. I tried NOT following the instructions as that was the case in most games, but quickly realized that was not it. And oh almost forgot the transition from main menu to gameplay was smoother than the butter, loved it.
