To confirm the dialog problem: When you talk to an NPC the sound effects are way too quiet. Opening the settings to fix it causes the mouse to toggle off, and you are stuck in a dialog box you can't interact with, unless you go back to the settings and while they are open, you can go over to the dialogue box with your cursor to get out of it, causing you then, however, to be stuck again.
The game looks perfect, and I really would love to explore, but the time limit makes it really unattractive to do so.
Keep the good work up!
