This game is written under extreme constraints. Specifically, it uses no quotation marks, including ones that would be used to give the game a title (so Inform defaults to 'Welcome').
So everything has to be deduced from the info you're given in object names and actions of those around you. Runtime errors are also a source of info.
This is quite tricky of a game. There are several layers of puzzle here. I solved a small chunk of the game on my own (around 20-30%) then went to David Welbourn's walkthrough, where I realized I hadn't understood any of the run-time errors.
Overall, this was a fun concept that was well-executed.
