Press the green flag to start! Your health is in the top left of the screen. Use A and D to rotate. Pressing space will flip your shield and gun. Eventually enemies will start spawning on the edges of the screen. Block the red enemies with the shield (Red line) and shoot the blue enemies with the gun with E. Press Q to spawn a shield to block purple enemies when they are near you. Block the orange enemies with the shield! If you shoot them they will explode and damage you. When an enemy touches you you take damage. When you lose all of your health you lose. When green enemies come at you let them hit you, they will recover 1 health. Shooting them or blocking them with either shield will destroy them and you won't gain any health. Survive as long as you can! Good luck.
When you start if your character doesn't appear just press the green flag again!
