Gamers have been enjoying Castlevania's eerie storylines since 1987, and the latest version of Castlevania for Game Boy Advance is one of the very best in the series. Powered by Game Boy Advance's 32-bit color graphics, Circle of the Moon looks great and sounds even better. The haunting music tracks and awesome sound effects are some of the greatest audio treats we've ever heard on a portable system. Turn down the sound on this one and you'll be losing a great deal of the gloomy atmosphere which is crucial to the Castlevania experience. Circle of the Moon relies heavily on the platform-jumping skeleton-whipping formula which led to Castlevania's initial success, but Konami has created some new gameplay elements which add to its depth. Instead of simply working your way from point A to point B in Dracula's castle, you can choose your own route through branching passageways and corridors. The gameplay is mostly linear, but you'll definitely make a few wrong turns before figuring out where you're supposed to go next.
