If you lag play here https://turbowarp.org/868181940 Kill the zombies with your sword by pressing space or making them touch your katana. You only get 30 seconds of slash attacks with the katana because otherwise you can survive forever. Press 2 to switch to shurikens and press arrow keys to shoot them. Press 1 to switch back to katana. There is a boss battle at 100 seconds survived which can only be beaten with Shurikens. Spotting a gold zombie is 1 in 1000 but will give you +100 health.
Inspiration from Thadny's Pasta Stan bread ops arcade but all coding and art by me. I am by no means a pro scratcher and this project was just made at school for fun.
