Well, it started promising, until I got to that stupid green keypad. I assume there's supposed to be a better solution than a brute-force hack through about twenty levels of a three-by-four matrix, but I sure as heck didn't see one. I think I got pretty deep into the solution before I got bored with it, and quit.
Something tells me it has to do with the upside-down box and the panel it's hiding, but I couldn't interact with that panel in any meaningful way.
Grrr. I guess I just haven't played enough of these games to figure it out.
