How to Play Wonder Boy in Monster World
Quick start
Guide Shion through villages, caves, and castles, gather clues, buy equipment, and collect keys and new abilities that open deeper routes. Attack at the edge of the sword's reach, use magic on groups or bosses, and revisit old areas after gaining movement powers to find hidden doors and hearts. Save healing items for bosses and upgrade weapons, armour, shields, and boots before entering each new region.
Controls
D-pad: walk, crouch, climb, and move the cursor. A: use the selected item or magic. B: attack with the equipped weapon. C: jump. Start: open the equipment menu and pause. From the menu, choose weapons, armour, shields, boots, magic, and items; new equipment can alter defence, movement, and attack range.
