There are 10 waves. You can use space your mouse or enter to shoot. and you can use "wasd" or arrow key to move. you win when you beat wave 10. To auto shoot press "E" to stop press "Space Bar." The green crates give you hp. The brown crates give you rapped firer. Try to be the fastest to beat the game.
Thanks to @gobmsm2 for helping me with some of the code, the thumbnail, the timer and a lot more. Thanks to @OG-Matthew for helping me with the thumbnail picture, the "Zombies in a wave," the cursor, and a lot more. I used 'Jackson Academy' for my tutorial to make this game. Tell me if you want me to add more waves. I am trying to add a high score system and a world record system.
