I’ve decided on my idea. You play the role of Karl, the Cosmonaut. Your tiny home world (yeah, great connection to the theme, I know) has drifted into the wrong part of the neighborhood – the part of the neighborhood where asteroids and rogue planets. Your planet comes under assault from asteroids and other celestial objects coming in from all angles! Your goal? Don’t be crushed. You can walk around and jump. If your planet becomes too big from other stuff crashing into it, it blows up. There will probably be powerups and stuff if there’s time.
Here’s some pictures that I drew!
