WASD to move or arrow keys and space to shoot. When you beat the game or if you die then double klick the green flag. Th black button is for shooting for mobile. Med kit heals you. It takes 3 shots to kill blue zombies 5 for green zombies and 10 for red zombies.
This is my first shooter game. I am now working on a game that has a sword. Sorry but can’t tell you more about it.
