Don't let the orbiting astronaut get hit by aliens or exit the screen! Arrow keys to move, space to change direction of orbit. Destroy aliens by smashing into them with the moon!
The original project is by @Aboot4. I added the alien-smashing bit. Update 15 January 2021: I noticed some of the health icon sprites had been messed up and fixed them. Not sure why it happened but it works now.
