I don't really have an ego, but I can appreciate that it might not come across that way. The way I see it this puzzle was meant to be easy with a theme I thought to be fairly accessible. It may not have turned out that way, and for that I'm sorry as it wasn't my intent to have a hard puzzle -- particularly as, if we're honest, the endgame is pretty boring really -- so I'm happy to provide hints to the theme as that still leaves the majority of the actual work -- clue solving, jigsaw entry, etc -- to be done.
All the same, I'll not contribute anything else to this thread from now on. But it really isn't an ego thing.
