The green area is sometimes a bit too hard for a normal mansion, IMO:
First of all, are there only two green keys? I cannot find a third one. If that is the case, will Jack not be able to visit all parts of the green area if he opens the green doors in wrong order? (This question also applies if there are three green keys)
#17496: I can see you are using the same kind of door puzzle idea as I did in The Caves and the Castle. Good
#17495: Nothing hard here - ASA Jack knows how to solve it.
#17494: Close to hard but experienced (and patient) players have played Midnight Mazes and Monsters 8-)
#17493: If Jack enters this room for the first time via the yellow door he knows nothing about the giant spider. A jump will lead to a cheap death.
My Jack, having been to the room above, assumed there would be a secret entrance to that room - and he was right - but there is absolutely no hint!?
#17292: Good puzzle, nothing so hard here.
#17293: Takes time to figure out how to kill the lone monster.
#17294: Again, close to hard. The zapper beam is difficult to avoid, at least for inexperienced (and rusty) players.
#17295: No problems here.
#17296: No problems.
