Use the WASD keys to move around. The 1, 2, 3, 4, and 5 keys are for your weapons, which you will unlock as you kill the zombies. Click to shoot, and if you get jumpscared by the damage screen, leave a heart. Good luck!
Notes: The dagger is actually overpowered, nothing can touch you because the zombies die instantly. So I would use the dagger if I were you. Credits: Song: The Cannery by Kevin Macleod
