Thanks for the comments, folks. It's really helpful in strategizing future chapters.
I agree that the story needs more exposition. And the taped message is a bit too garbled and vague. (There's such a thing as being too mysterious, I guess.)
As for gameplay, I'll avoid puzzles for puzzles sake and try to tie them into the overall plot and character motivation. That's good advice.
Full screen only seems to work when you launch the game outside a web browser, so I'll have to work on that too.
