Hey guys, I developed this little game about a year ago in a custom engine made in c#. I never released it until now, you can generate solar systems, look at planets, watch their atmospheric contents change and evolve as well as watch the life forms that evolve. You can also view the history of planets, and save and load solar systems.

Let me know what you think :)
