What is Galactic Simulator?

This idle clicker and sandbox simulation follows a galaxy from an observer’s perspective. You use a small set of click actions and optional automation to simulate celestial bodies and civilizations as they develop over time, with systems based on the Fermi Paradox, Drake equation, Great Filter, and Kardashev scale.

For you if...

+you like watching systems develop with little input
+you want space simulation based on scientific theories
+you prefer casual sandbox play with online co-op

Not for you if...

−you want fast, input-heavy action rather than idle progression
−you dislike clicker mechanics or automated systems
