So first, what you do to move is you use the arrow keys. You can't move backward so it is just top, left, and right arrow keys. To shoot and kill the zombies you have to press space and it has to hit the red zombie 3 times for it to die. The Green Zombie you have to hit 6 times. I also added when you press 1 it switches to a pistol. When you Press 2 it switches to a Machine Gun. You have 3 lives. When you lose all of them you click start again and it resets. Finally, you have cash, so when you reset it, it resets cash too. Heart and Star and Enjoy.
This is a common game; I actually have seen a game like this on Scratch, So then I decided to make my own game. Thanks to my Essential Tech Teacher in School, I was introduced to Scratch and How to use it. I hope you enjoy and I thank My Essential Tech Teacher Keep Coding!
