The second NES game released by Enix, the first being the forgettable Door Door. I don’t know much about this game, but it’s by Yuji Horii, so you know it rocks. At first it looks like a standard text adventure, but I hear later on it becomes a weird Wizardry-style dungeon crawler thing.

DvD adds:

This is the first adventure game released on the Famicom. Yuji Horii ported this, his successful NEC PC-8801 game, to the Famicom to determine whether the Famicom action game crowd would take to an adventure game. The game did quite well. Because of this, Horii was able to release the game he really wanted to make for the Famicom, the first Japanese console RPG: Dragon Quest.
