Of course, that exception has to do with the visual design, which isn't really new to begin with. Gold Knights II uses the same visual design from Ultimate Ghosts 'N Goblins. It's polygonal rather than sprite-based, but it's still recognizable as an installment of Capcom's classic medieval action franchise. It's a decent-looking iPhone game; the character designs straddle the fence between traditional and inventive. Arthur and Perceval are designed as GnG characters through and through; each hit they take removes a piece of armor, until they are only wearing boxer shorts. Boss monsters look great, and every enemy goes down with what looks like a small fireworks display.
Gold Knights II's sound design doesn't fare quite so well. Attacks (normal and special alike) sound appropriate, but nothing out of the ordinary. The soundtrack is disappointing. It's been a while since I've played a traditional Ghosts 'N Goblins game, but I remember better music. In fact, it was so much better that I can hum a lot of it from memory. It hasn't been five minutes since I last put Gold Knights II down, and I can't remember the music.
