This was Les' second attempt at writing an adventure game; dating to at least as early as 1988 and produced when he was in his very early teens. It's unclear if it was ever released.
An unofficial conversion of the ZX Spectrum version is available for Atari 400/800; ported by devwebcl.

In the ZX Spectrum game, there is a bug at the end whereby the uncorked bottle is swapped with the golden mushroom. This fails if you don't have the uncorked bottle with you, but the message implies that it has worked. It should have swapped the spore with the golden mushroom. If you have the database file, you can fix this in the PLAN SPOR action by changing SWAP 14 12 to SWAP 11 12.
