What does alpha mean?
Universe Sandbox ² is still alpha software. We're not done fixing many of the issues and improving it. There remain many bugs, and you, the early access user, will help us uncover even more. Buying-in early means you won’t have to wait to explore the many new and exciting features that are already in place, but know that all of the final polish won’t be there yet.
