Inspired by an old flash game "Boxhead 2Play Rooms". Survive waves of zombies spawning every 10 seconds and unlock weapons as you kill the hoards. How long can you survive?

Controls: - WASD movement - Space shoot - 1 Pistol - 2 Uzi (once unlocked) - 3 Shotgun (once unlocked) - 4 Wall (once unlocked) - Q and E to select the last and next weapon

edit:
made a new build because the ground was kind of shuddering and I didn't notice on my laptop's display, but did notice on my desktop and it made me a little sick. I changed the ground pattern to attempt to fix this issue
