Excellent module. I recommend not pushing for the players to activate the dimension changing device, let them come to it on their own time.
Thanks for the comment! Glad you enjoyed these dungeons.
What system and setting have you ran it with?
I only ran it as one-shots. I did not push the players too hard, but, as these were one-shots, they were quite eager to get into dimension hopping fast, as it was the main "gimmick" of the adventure.
