I might not be the best person to review this game since I have no experience of the retro-hack'n'slash RPG scene the game apparently parodies. Some people might enjoy playing this more than I did.
Calling the game interactive fiction could perhaps be questioned. The Z-code parser has been reduced to six commands; gameplay consists mainly of primitive randomized combats and moving around the map; the story is nearly non-existent; items have rarely any descriptions (on the plus side there are many library messages so the items look like they were described). It felt more like playing a low-end Nethack clone than a work of IF.
Humor is absurd, even surreal (try talking to your bag) - mostly I didn't get it but as I said before, people with RPG experience might be laughing their guts out. The accompanying material is extensive and at a glance looks exquisitely made so an additional star for that. One might ask if the material was made to support the game or is it the other way around?
