Gameplay is fully sandbox and very fun, focussing on creating your own buck-toothed utopia in a challenging environment.

When you discover that you can build buildings on top of buildings or supports to enable another level of construction above your city (Coruscant like) it becomes a whole different story, one of the next entertaining things to think about is the possibilities of redirecting rivers in your favor, that is awesome, the good thing about all these projects is that they take time, time in which your mind has a single objective, and it is not a small one, your head is always finding more things along the way to entertain itself with and that promises hours of fun.

The game's graphics/CPU optimisation should be improved to allow better fps for larger cities.

Once you do that on each map, the rest is just colony optimization, which is where I spend most of my time.

* Runs well on Linux using Proton.

* UI ranges from "usable, but rough" to "almost unusable", depending on how advanced you are in the game; not everything has a keybinding, most icons are just light brown outlines on dark brown background (barely legible), and you'll spend many hours hunting for some buildings placed in some strange and not-really-fitting tab until you memorize everything, and then realize it could've used color coding or more menu levels or just a configurable hotbar etc. (there are probably mods for it :)
