Thanks, again. The puzzles are well paced. They're difficult for me, but I can solve many of them without help, so it's a good experience. I don't think I would have ever thought to connect the two objects to advance from the game state that I asked about, so I did really need the hint.
I don't know if there's an unwritten rule about authors helping players. In case feel free to stop me.
I don't know, either. There doesn't seem to be many customs about asking for and receiving hints on this forum, that I can see. I wonder what the customs were like back in the height of rec.games.int-fiction. I think I read something once that said a lot of authors don't like their beta-testers giving hints to players.
