Levoid's Star System Generator is a one-page tool to determine the basic outline of a solar system, specifically the composition of planets, quantity of moons, and color of the star. I made this tool as a component of a space exploration tabletop game I'm working on, but it started taking on enough life of its own that I figured I'd release the initial version on Itch.io. I plan on developing a fuller version that explores planetary biomes and features, as well as orbital features such as rings. That version is a whole lot larger than 1 page, so it may take some time to come to fruition.
