Great idea needs work – Marching Band vs Zombies Review

I saw this and thought it was an amazing idea. The problem is that when playing the game, my character dies at completely random times, even when he's not touching a zombie, a fire or anything at all. I can't play for more than about 30-45 seconds. This needs to be fixed ASAP. I'm playing on iPhone 7.
