I enjoyed Waiting for the Light a great deal. Here are my thoughts on what it all means:
SPOILER
The hints come mainly from the game show section. The question about David Lynch is the clue to the game's style, and conception- it is a dream-like metaphor exploring the psyche of the narrator. The central conceipt of the game is hinted at by the question on Robert Plutchik- his wheel of emotions provides the colour-code for the games exploration of how we choose to react and deal with our internal life and feelings. The aim is to deal with each emotion (represented by a different colour) not by negating or affirming it, but by harmonising it- to bring all the colours together to White. Each section challenges you to do that- for example by allowing the arguing couple to find a real, non-superficial answer to their problems. If you do all this, you escape from the darkness (which the "bad endings" represent) of repression or the un-moderated id, and reach solace and balance/ light. As a note- and a final joke, the page entry on which you do this is, of course, 42 - Douglas Adam's meaning of life!

So there you go. I thought it was an elegant and interesting composition, that reminded me a little of Adam Cadre's Photopia. Nice work!
