Instructions
SPACE/fire button - Shoot
When you hit a zombie you get money. When you have enough of it you can upgrade your gun. It might be a bit buggy after you get your shotgun because @RCrafter hasn’t coded anything after it.
Notes & Credits
This is a primary work of @Rcrafter, improved by me.

Note to @RCrafter:
You don't have to include the blood II function, I just put it there for fun :)
I shortened the script and added some mobile controls (the fire button).
