Thanks for the feedback! I'm glad you enjoyed it! I think you're right that the placement of the pacemaker is a little awkward, having it in the middle bottom is good advice. I might want to make the zombie heads contrast in color more from the background too, maybe put a bright colored bar behind them, anything to make it easier to track just from the corner of your vision. Great job on your game too! I sense a "best overall" coming ;)
