This is the beginnings of my pico-8 homage to the classic SpaceWar!

I wanted to create a version for more than two players. If you play it, I definitely would love to hear what you think and welcome suggestions.

Enjoy!

Like it! Good start, and good idea.

My first suggestion would perhaps be ability to set or vary the gravity effect.

Also, what would be really great would be the option to use CPU controlled opponents...
