Thank you. I was happy with it after spending a lot of time coming up with convoluted mechanics for making the wish then saying "Nah, just make it a simple die roll."
I hope some of the puzzle elements aren't too vague for the GM to understand. After finalizing, I realized it might not be clear that the belt needed for room 11 is found on the machine in room 18, ensuring that without clever actions on the player's part, the power engine needed to reach the conclusion can't operate without shutting off climate control, endangering everything in the dungeon.
