If that was in the original game (which I did play it a couple of times) I absolutely don't remember it.
You're right of course about the limits of the point and click and forced view nature of the game. A lot is hidden / cannot be explored as thoroughly.
It looks pretty right to me. I'll probably pick it up (after already having the original and the steam version).
The golden ball thingy in the bottle village? That's this floating "cage pyramid" where you can go up with a swing like elevator. I'm lacking the words to describe it better.
It seem I forgot most of Ghens world tho.
