Woah, that is intense! The balance is really well done, it is non-stop action, whether you're on the hero side or the zombies. It's also very cool to have a boss, several weapons, and even different kind of zombies after a while! I did not pay attention at the bars on the top left, I couldn't read them anyway in the middle of the fights, but I still manage to survive anyway. Overall I had fun playing this, well done!
