Nice concept. I'm especially pleased by the merchants that change their prices.
Most dialog boxes are rather empty and the bottom button row is crammed or overflowing. You could still tweak the layout a little bit.
Bugs:
- Clicking a button does not always do something.
- The load game dialog is not filtered :( .
- Loading crashes the game. To be more precise: You have to enter a full file name (including .db extension), otherwise the dialog will not close. The game then appends the extension and opens another file. You can trick it into working if you create a file without extension and select that.
