This is the original Wario Land 3 for Game Boy Color, playable on the Advance. It's a puzzle-platformer where Wario explores a mysterious cave to free a trapped spirit. The game is absolutely worth playing for its inventive, non-linear design.
It's a chill adventure focused on exploration over fast reflexes. The core twist is that your powers and the world change based on finding music boxes, altering levels you've already completed. This creates a satisfying, Metroid-like loop of discovery. Give it a shot.
