In this game, you build on your planet with all of the building materials, and you can also fight between planets using planes! There are three planets so far: Neoterra (New Earth), and Xenoterra. Neoterra has humans, and Xenoterra has aliens, and Silacatopia has silicon-based life. There are even moons you can colonize!
In the future, I will add more features to this game, and maybe even add new planets.
