arrow keys to move, space to throw axe, only 1 axe per second, zombies move faster every 12 seconds, put time in comments if you want, and you have 162 health, and .3 second invincibility after each hit taken.
i'll add more difficulty options soon, maybe today if i can. if you chose a difficulty after I add them, put it with your survived time. i will eventually make music in it, with a list of songs and music. if you want music added, put the link in the comments, no more than 15 minutes.
