This game was something we had to finish, so we got some presets and had to finish the rest of it ourselves.
I decided to add some references to games or series that I loved, in this case that's Rick and Morty and Mario Kart and Mario and Luigi, Partners in Time.

You can also see Wheatly from Portal 2 in the background too because I love Portal.

This is what makes the ships fly, they get a random Y position once they reach the end to make them appear in different areas instead of always the same place.

Also when you click on them, it sets them back to the right, changes their Y position again, gives them a random speed and then turns them back on.
