I had to relaunch a couple times before it ever gave me sound, but otherwise it worked pretty well. I really like the idea, hope you're still working on it! I'd like to suggest if you are still working on it that you refine the item inspection a little bit:
*consider changing the text from 'pick up' to 'inspect', to distinguish from where you use 'pick up' to mean add to inventory
*since we can't walk or look while inspecting objects, consider making the mouse rotate the object by default rather than requiring the player to hold shift. Seeing the object move when you wiggle the mouse will make it much more clear that we are in 'inspect mode' and that we should not expect to be able to move or look around until we exit this state
*since objects are inspected a fixed distance away, and we must stand near them, and objects are usually on something, consider setting the object being inspected to arbitrarily draw in front of everything. As is, it's too easy to visually lose the thing you're inspecting inside the table it was on, meaning you need to close inspection, reposition, and try again
