The main puzzle behind this game drove me crazy for the main reason that it is not something that people would do ordinarily; that is to say, (Spoiler - click to show)giving the hermit back a key to get your dollar back after you've broken it and repaired it with glue. Also, the idea of buying a clarinet, using it, then returning it to get your stupid dollar back is awful. I don't know what country this author lives in, but this is not civilized behavior.
The descriptions in this game, at least in the beginning few rooms, are dreadful. For example, "Above your head tower obtuse angles of gray-shining metal, each segment tilted a different way and so bearing a differing depth of shadow. Higher still a riot of white sunlight twinkles on geometrical patterns of rivets, and beyond, the ceiling is hidden in a glowing haze... presumably." I can't begin to describe the sheer awfulness of this prose so I won't.
Also, there's no back story as to what this Holy Robot Empire is or why you want to kiss the Pope's ring. Just go with it.
All of these criticisms aside, the game has few bugs and WTF moments. It's short but irritating.
