I liked this, although after a few runs it starts to feel repetitive because there's not a lot of depth yet. I played on mobile even though it wasn't really supported and was pleasantly surprised that it worked pretty well. The only difficulty I had was with scrolling the perk and codex windows, which didn't respond consistently.
I think I've seen most of the content in what feels like a demo. I unlocked only two of the base city types even though I found all five of the rare city types. In fact, I think all but one run started with the city of balance. It's apparently incredibly hard to be out of balance even if you try, which is funny.
Also "Guidance of the Codex" doesn't seem to do anything. Every city only ever earned one memory when resetting. This included the run after I earned this perk when I unlocked the city of the golden mean for the first time.
Early on, I saw that some notification popups were still in Japanese. Mostly they seemed to be higher level building fusions. For instance, Farms seemed to upgrade to Farmhouses, Watermills (which look like windmills on the map), and then something else. I couldn't reproduce it later though.
