Very interesting sim! I liked the calming music and the very soft, readable UI colors. I had troubled understanding what I was supposed to be doing or what my goal was for most of my playthrough, but I was able to keep it going all the same.
Some critiques I had - the UI is very clean, but I think it would help to simplify it a bit. Currently there is a LOT of information on screen at once, and not all of it is necessary to be seen at all times. Job Allocation, for instance, could be collapsed out of view when not being adjusted. I'd also consider if every bit of information needs to be communicated in text. Sometimes it is quicker to understand and more intuitive to use symbols or icons which correlate with what players are seeing in the game world itself.
The other thing I wish I would have seen is more feedback as to what is going on in the game world. There are clearly many interesting systems happening at once in this simulation game, but it all happens invisibly. I would love to see people moving about the map, things being built, etc. The day/night cycle felt unnecessary as well, and got a little difficult to look at especially on high speeds.
Overall I think the game has a very nice look and feel and is very relaxing to play and look at. I'd really enjoy seeing this game subvert some of the civilization sim genre tropes and add some interesting mechanics and outlying experiences. But the graphics, ambient sounds and narrative are all very cool!
