This game was written as a learning sample of the ZIL language. It was written over just a few days.
As such, it is small and lean. But Welch has managed to put a few clever puzzles in.
I was unable to solve this without a walkthrough the first time I tried it. After the walkthrough, which is very detailed, I felt like the game required a number of fairly mean actions, but with suitable rewards.
I find this game most interesting as an example of the ZILF language. I wonder how many of the standard responses were hand-coded, and how many part of the language.
