If you like it, be sure to also check out Andrew Plotkin’s ‘Lighan ses Lion’ [0], an entry in WalkthroughComp run by Emily Short [1]. It’s not a game, just a transcript of a fictitious game, but well worth checking out for a chuckle... or as a brain teaser.
Also, the Beast puzzle in ’The Edifice’ [2] by Lucian Paul Smith comes to mind.
