issues:
The windows loading symbol appears whenever the game is loading. This basically seems to indicate, that the UI thread is blocked by the loading. Try asynchronous loading to avoid blocking the UI thread.
Either in the last training briefing or the first main campaign briefing (I'll check this again and edit this once I know which one) has the last sentence spoken twice by the voice actor. The 2nd version slightly changed, indicating an earlier translation maybe?
Suggestions:
The active unit highlight is still a bit dark. it would be nice to make those units glow even more, maybe let the hex field borders glow or something to make sure no unit is missed.
Make the entire manual acessable in-game, not just the compendium entries. Also why is there no icon for unit disbanding, just a hotkey?
Core units and helper units are not easy to distinguish with the current border color difference in my opinion. I thought the PG solution with black vs white strength font color was better.
The weather icons are pretty bad IMO. Somewhat bigger and more clear representations of the weather would be better. At first glance I don't see what they are supposed to represent.
The entire UI text is very small. It's sometimes hard to read.
Those are my comments, otherwise great game and so far more challenging than PG. So keep it up
