This game intimidated me. You are a janitor whose job is to clean up after adventurers (i.e. reset the game world after each player). This is an idea that was present in Adventure, the original text adventure, but it has been taken to a fun level here.
The problem is that setup is hard. There are two sets of doorways, one natural (leading about the game world), and one in a grid system (backstage) that is very confusing. Also, it's hard to know how to start using your mimesis disrupting mop.
Once you get into it, this game is fun. You have to use clues to guess how things used to be, and reset them to that state.
A very fun Zorkian game. Unfortunately, it contains ASCII art of a nude woman, but its completely avoidable.
