If you are on mobile, use the arrow keys on the project to move and tap the blue circle with red lines to shoot the enemies. if you are on a computer, then you can use the arrow keys on the keyboard instead and press the space keyboard to shoot. If you get hit three times, it’s game over! Fullscreen recommended.
All of the coding was by me https://scratch.mit.edu/users/ArcticFoxRocks but thanks to https://scratch.mit.edu/users/CactusBoy16 for the idea for the arrows and https://scratch.mit.edu/users/sveng0001/ for the outer space inspiration.
