A lot of the staff that worked on this game were the creative forces behind the early Megami Tensei games, including the game designers, programmers, and composer. Which you can definitely tell with its first person dungeon segments and that very distinct early Atlus sound driver (Megaten 1 & 2, Erika to Satou, Dungeon Explorer, to name a few examples). This is one of my favorite more "under the radar" gameboy games, so I'm glad more people can try it out atleast. It could definitely benefit from a save or continue password system of some kind, but its a pretty impressive showing for an early gameboy title.
