Deep Dungeon III: Yuushi e no Tabi

As the name suggests, you can't get anywhere without Japanese. Or almost nothing. You choose your hero(s), then walk around the maze, the view is like in a 3D shooter, out of your eyes. Walk through doors, buy things from Japanese junk shops. Sometimes you'll come across unfriendly skeletons, with whom you'll have to engage in verbal combat. The sound is simple, and the graphics are not far behind.
