Castlevania: Circle of the Moon is a spectacular game that launched with the gameboy advance. It displays some of the prowess of the GBA, with crisp graphics and stunning music. The music in CotM is probably its best feature. The gameplay is where this game shines the most however, because this game is a superb example of enjoyable, non-linear gameplay. As you go explore the castle of Dracula, you can visit many side areas and nooks and crannies. The only qualms I have against this game is its difficulty (small) and its lack of extra features. The replayibility is enhanced by the inclusion of special playing modes, but more could have been done. I'd recommend this game to anyone who enjoys side-scrolling action games, as this is probably the best one for the GBA.
