If you are using a touchscreen, move your finger up and down on the screen to move and use the automatically on auto-shoot (top left of the screen) to shoot. If you are using a computer or laptop, use the up and down arrow keys to move and space to shoot. You have 10 health (bottom left of the screen). If an enemy touches the left side of the screen, your health decreases by 1. Shoot the enemies to prevent this. The goal is to survive for as long as possible.
I made this because the space battle 4 did not seem like the place to end. https://scratch.mit.edu/projects/423913514/ https://scratch.mit.edu/projects/442008059/ https://scratch.mit.edu/projects/442008847/ https://scratch.mit.edu/projects/511051671/
