Classically-Inspired Arcade Action

Two pet pilots enter, one succeeds! Duel in spaceships using rockets to try and knock out the opponent. Use the gravity to your advantage. Go for a high score in Arcade mode, or prove who the better pilot with friends in local multiplayer Versus mode! This game was designed to be enjoyed in short intervals.

Crowd-Funded Development

This game started as a weekend distraction, but could have so many more features. As funding reaches each new level, I will continue development. Interested in seeing this game grow? Help me reach these goals!

I wanted to take a quick break from developing Kingdom Bash, and wanted it to as small a game as possible, so why not start at the beginning of video game history! Space Duet is inspired by Spacewar!, one of the first video games, created in 1962. This is my take on it!

this looks really interesting! i don't suppose there's any chance of a linux version?

Thank you! Though I am able to build an Ubuntu version (using GameMaker Studio 2), I currently don't have the means to test it. Unless there was a big demand for it (and the game in general), I would consider it, but at this moment it's not going happen.

Again, thank you, any interest in my work makes me happy. ☺
