Enjoying the game so far! I like the ultima-like feel to it, but I feel like there's a few room for control and quality of life improvements.
First, make sure your money is displayed on all screens where you can buy or sell things.
As well, it's hard to track what is happening in combat on the screen. This is not easy to fix with the roguelike presentation, but since you can have multiple characters fighting multiple characters - it might help to slow down the turn-by-turn action somehow.
As hunger and thirst are important, perhaps make sure every settled place has a well, perhaps some opportunities to get both rest and a meal for cheap.
The exit to each settlement should be more clearly marked on the map.
Increase quick links using the mouse - clicking to use rations for food, water for thirst, and potions for healing would be handy.
