Myst is the epic puzzle game whose puzzles will take you hours to solve. Unless, of course, you know the answer. Although you'll encounter many brainmelting puzzles when normally playing through Myst, all the game really requires you to do is flip the eight switches around the island, get the blank page and bring it to Atrus.
One of the hardest things about this is the fireplace code which must be obtained in order to get access to Atrus. However, this being a TAS, the code is known and is entered in the most entertaining fashion the author could think of.
This TAS plays through the Sega Saturn version of the game, flipping all the switches, getting the page, and entering the code in the fireplace in record time.
