It would be hard to believe that this wasn't inspired by Zelda at least in some ways. The game is more linear than Zelda, and features a few different perspectives. The cave levels, which I would equate to Zelda's dungeons, aren't very interesting and neither are the bosses. Overall I think it's a solid action RPG that tried a few of its own things with varying success which I think you would see carry over into Compile's The Guardian Legend a year later.
