supplementscene: I suppose it's how that comic timing translates into English. I think I read something alouding to the fact that the German voice actors were pretty big hitting. It sounds like it's one of those to play with a walkthrough unless you have a very high patience threshold. I'm guessing there's nothing to highlight all clickable items?
MarkoH01: It's been a long time since I played them but afair no, highlighting hotspots is a thing that is a "pretty recent" (yes, I know these are now also quite old but for me ... well, you get the point) development meant for casual gamers (although you may test it yourself using one of those links above). Originally point and click adventures were meant for gamers to get stuck and muddle through from time to time - maybe even do some breaks and come back later. Yes, you'll need a lot of patience for those. I do remember playing some of those old school adventures so long until I finally was convinced that the game must be broken and it's impossible to continue. I then went to a store (because there was no internet back in the days) and looked it up in a walkthrough just to see how obviously the solution in hindsight was :)
I have a love hate relationship with the genre. I started with a few Lucas Arts games I couldn't get into because I got stuck. Then came my true love in Broken Sword, which I played with my mum and actually completed it alongside it's 2 sequels. Generally I gravitate to story rich games with logical puzzles where cursor browsing doesn't spoil the game. I got back into the Lucas Arts games and I didn't really enjoy them as the story and characters were comparitively uninteresting. I loved Gabirel Knight 1 and 2 for Jane Jensons writing, although I can't believe some of the puzzles in the first game were solved without walkthroughs, at least 1 seemed impossible. But I enjoyed her writing in other games like Cognition Erica Reed and Moebius too.
So I suppose I'm maybe not a true fan of the genre and a bit or a casual gamer, although I hate hidden object games at the same time.
