Hey there! Things started out pretty strong but I'm really sorry to sound overly critical ^^; 
I was entirely stuck on game progression and I'm unsure exactly why - every map exit took me back to the stairs. I also defeated the first encounter but nothing beyond it seemed to work. The man in the banquet hall won't do anything and I can't understand what the conversation is about because the text is cut off due to being too long for the text boxes, which was a common problem.
You can walk on basically all the furniture in the dining hall and you can interact with the food with a take/leave food question, but the food not only changes graphics depending on interaction angle (usually due to not setting it as an inanimate sprite with a fixed direction) but actually doing either one of the actions doesn't do anything. You can also re-trigger the dungeon exit dialogue by walking into the tile in front of the right side of the door.
I do think there is an interesting idea buried underneath but I couldn't get close to finishing it to find out ;w; Thank you for submitting though and I hope I don't sound too mean. I'm trying to be constructive ^^
