Thanks for your feedback! I've fixed the problem with the dining room, and I'll be sure to go through the game again and find the spelling mistakes you're talking about.
I wasn't able to replicate the problems you had with the sound and full screen mode. It might be a problem with the web browser — which kind of web browser are you using?
Also what about the ui is puzzling in particular? I know it's a bit unique — I wanted to be a bit different with it — but I'd still be interested in hearing your thoughts so that I can know how to improve for future projects.
