Found out about this game thanks to the Reddit thread on r/linux and saw you wanted some feedback, here are my initial thoughts:
Having a little bit of text that you can skip the starting cutscene would be appreciated. I found out you could do so with Esc, however I don't see any text stating this is a thing you can do.
The arrows in the options menu don't work for FPS Cap and Background FPS, this makes sense as only going up or down 1 in these options wouldn't be very useful. However having buttons that don't do anything is confusing, they should probably be removed (or made functional by increasing or decreasing the amount by 10).
The hovering over things for more information (such as the already mentioned FPS Cap setting) is useful, however it takes just a bit too long that many people will probably assuming the game doesn't have those. I suggest reducing that time if possible a bit.
I found the scrollbar in the settings menu to be just a tad thin as well, if that could be widened that would be useful.
The dialogue text when you start a new game is too slow imo, I was tempted to keep clicking to make it appear faster but that only skips to the next box.
While I like all the time options, I wish 0x had a dedicated button, so that I could quickly identify how to pause the game if the need arose.
I like that windows can be dragged around, that is very useful, I do wish that the windows snapped to each other, as that would make organizing them easier.
The color for resources that are in range of a building blend in with the grass too easily. The color should probably be changed, or an icon should be added.
The fishing place says to make sure there are fish in range, however it's hard to tell if fish are as I don't know what I should be looking for. Fish should probably be made more obvious, even if only when placing a fishing place.
When using Q and E to pan, if I hold both and then release one, the panning doesn't happen until I release the 2nd key and repress it. This is odd behavior, and probably unintended.
When selecting people to put in a new hut, having the job they work listed would be extremely useful, as I want to put people in huts near where they work. As it stands now, I have to open the workplace and check the names of the people who work there.
Overall the game shows promise, and I'm very interested for the full release.
Best of luck with the game, and I hope it sells well!
