How it plays
The game is presented from a side-scrolling perspective. Nathan explores Dracula’s castle, defeats monsters, collects map items and cards, and searches for the kidnapped Morris Baldwin.
Plan your run
Explore thoroughly and revisit earlier rooms whenever Nathan gains a new movement ability. The map helps identify unexplored branches, but hidden walls and optional rooms still require careful searching.
Experiment with DSS combinations rather than relying on one setup. Keep healing items for bosses, use save rooms frequently, and level up in areas where enemies can be defeated safely and consistently.

Castlevania: Circle of the Moon is a gothic action-adventure platformer developed by Konami Computer Entertainment Kobe for the Game Boy Advance. It follows Nathan Graves, a young vampire hunter who enters Dracula’s castle after his mentor Morris Baldwin is abducted during a resurrection ritual. The game uses an exploration-focused structure, with interconnected rooms, hidden routes, bosses, and ability upgrades that gradually open previously inaccessible areas. Its central system is the Dual Set-up System, which combines action and attribute cards to modify Nathan’s whip and grant elemental, defensive, or movement effects. Circle of the Moon was well received at release for bringing the series’ exploration formula to a handheld, although its dark visuals were criticized on the original, unlit Game Boy Advance screen.
