I could see myself using enemies from that game, but beyond that... It doesn't stand up to the kind of tiles people use now. But! For a slightly "updated" looking classic style quest, the tiles would work perfectly. Also, the perspective is more realistic than that of any 2D Zelda, and it gets points for being consistent (spelling?) with the overworld(I'm looking at you, Link's Awakening). I find the dungeon tiles amusing. I want them. Just to stare at them.

Of course, now I must hunt this game down and pwn it. It's a principle kind of thing.
