Yes it is Zork, except Zork came from Dungeon
Kudos to those who realized that this is Zork. However, this was not taken from Zork. Zork was a commercial personal computer version of the already existing Dungeon game from the minicomputer world. As a kid I was playing Dungeon at my dad’s work before the Apple II was even wide spread and before Atari and Commodore computers were even for sale. This is a fun nostalgia game to play on the phone !
