The punctual flaws that it displays in the main components of its fabric turn Circle of the Moon into a Castlevania installment that is good, but not great. The transplant of the Symphony of the Night formula into a portable is, in a way, a success, because the marriage of non-linear exploration and RPG elements makes traversing Dracula’s fiend-infested castle an appealing experience filled with discoveries, secrets, challenge, and unguided progression. However, the game could have certainly been more careful with the way it handled its elevated level of difficulty, its visual presentation, and the implementation of the central gameplay mechanic that it builds to call its own. With those problems in mind, Castlevania: Circle of the Moon cannot be universally recommended, as the Game Boy Advance itself holds a couple of entries of the franchise that are easily superior to it. Nevertheless, there is great enjoyment to be found in its imperfect Gothic quest if one has fondness for lack of linearity, is able to ignore its shortcomings, and can deal with some moments of grinding.
