Hey, thanks for the detailed feedback! It is really appreciated. I could try to implement a sort of mouseover hand to indicate interact-ability in the future. And yeah, the item you get from the certain someone is probably the most difficult to figure out how to use! This could perhaps be helped by using more specific item names (non-spoiler example: If I gave you a handle that was meant to open a window, I could call it "window handle" rather than just "handle").
I'm glad you enjoyed the art and sounds, and that your curiosity was a bit piqued :)
