I like the aesthetics. You could go all in on it and make the map look like in paper format too instead of looking like zelda 2. The UI is pretty good.
You can tone down the white to #f2f2f2 as usually it's the standard color for "white" backgrounds.
Moving on the Map sometimes feels not responsive, I have to click again.
Combat is confusing as I don't know when I'm allowed to use the context menu, when can I pick an enemy to attack etc. The mouse randomly not responding doesn't help.
While in town "Party" tab is doubled. It also seems like an option I should be able to access while on the Map.
Buying leather prompted me that I paid 960 gold, which was my remaining gold.
Clicking "File" on top closed the window moment after opening the menu, no crash message. I don't know why, as that didn't happen the second time. I'm quite sure I didn't click Quit.
