The Legend of Zelda: Oracle of Ages

A puzzle-leaning companion to Oracle of Seasons, built on the Link's Awakening engine with a time-travel mechanic via the Harp of Ages that anchors its dungeon and overworld puzzles. It plays as a standalone roughly 15-hour Zelda adventure, but linking it with Seasons through a password system unlocks a more comprehensive story and a true final boss. A worthwhile, somewhat overlooked handheld Zelda well worth revisiting.
