User reviews
Nice game. But you really need to plan
Couldn't be better as always
Addictive. I sign in every chance I can
Such a new take on an idle game. I love the idea of making a new world livable.
I really like this! It's fun, uses some real science and has cool effects. My only two suggestions would be: 1)allow for us to pay to reverse time in case we make a mistake, like flooding a planet. 2)have more chaos scenarios, like the ones about aquifers and meteors falling.
The game has a steep learning curve, but that is a testament to it's detail and complexity. The graphics are really great. This is a most enjoyable game!
