Hiya! Thanks for trying my game! And thanks for the feedback!
I'll consider getting the game to default launch in windowed mode, to make it easier for people to choose which display mode suits them best.
I'll take a look at the metal tag on the chest. I think there's a response for it, but I could probably add some synonyms!
Page 10 of the manual has some conversational topics to try! The game doesn't prevent game progress if you fail to ask the proper questions, asking questions will mostly just give more background information about the characters and situation.
Thanks again, and best wishes! -- Julia
