My shortest walkthrough: Merlin's Castle (Apple II - General Masters)
"The kingdom is in shambles! Crops are disappearing! Strange things are happening everywhere! The culprit? None other than Merlin the Magician! It seems the absent-minded wizard of King Arthur looked into a mirror and hypnotized himself into a fit of evil pranks. In desperation, angry citizens have dispatched you to the ancient castle to zap Merlin with his own wand. Plan each move carefully, then issue a two word command to the computer as you inch closer to the wand. Now - pull the rope, summon Merlin, and ZAP - you've disintegrated the old follow for a nice long nap!"
Merlin's Castle (https://mocagh.org/loadpage.php?getgame=merlinscastle) was a graphics adventure game published by General Masters in 1983 for the Apple ][.
Hope you enjoy the walkthrough!
