Castlevania - Circle of the Moon (USA)

Released in North America in June 2001 by Konami, Castlevania: Circle of the Moon is the first full Castlevania title released for Nintendo’s Game Boy Advance handheld. Launched as a launch window title for the GBA, this gothic action-platformer quickly cemented its place as a fan favorite among retro Castlevania fans thanks to its rewarding difficulty, unique magic combo system, and atmospheric dark tone. The game follows Nathan Graves, a young vampire hunter in training, as he ventures deep into Dracula’s cursed castle to rescue his kidnapped mentor and stop the dark lord from completing his resurrection after a 100-year slumber. Striking a balance between the classic 2D action of early Castlevania titles and the open-world Metroidvania mechanics the series became known for, Circle of the Moon offers hours of exploratory gameplay for handheld retro fans. Its most defining feature is the innovative Dual Set-up System (DSS), which lets players mix and match two types of collectible mag

Game Guide

Mastering Castlevania: Circle of the Moon starts with understanding how to leverage its unique DSS system, the core of your power throughout the castle. Start exploring every side path and checking breakable walls early to collect as many action cards and attribute cards as possible—even common card combinations can drastically simplify tough encounters. One of the best early-game combinations for new players is the Mercury action card paired with the Mars attribute card, which extends your whip range and boosts base attack damage to make clearing out common enemies and tight corridor sections far faster. If you’re struggling with low health or difficult bosses, head to the Underground Waterway early to farm low-level skeletons and slimes for experience points and random card drops; this area is easy to navigate and lets you level up quickly to boost your HP and attack stats before moving into harder zones like the Clock Tower or Necromancer’s Laboratory. For boss fights, stick to long-range damage combinations like the Venus action + Thunder attribute pairing, which lets you deal consistent damage from a safe distance while avoiding the large, fast attack patterns most late-game bosses use. When you reach the final boss battle with Dracula, come prepared with at least three full health potions and the Neptune + Pluto card combination—this combo grants you temporary invincibility to his devastating instant-kill laser attack, which is the most common cause of failed runs. Always save at every save room you find, as the game has no mid-dungeon checkpoints, and dying will send you back to your last save with half your maximum hearts, so preparation is key to beating this challenging retro classic.
