Kirby & the Amazing Mirror
Release Date: 2004
Genre: Platformer / Metroidvania
Players: 1–4 (Link cable)

Description - Amazing Mirror is basically a Kirby Metroidvania, and it is one of the most unique games in the whole series. Instead of moving through a straight line of levels, you explore a large connected world, unlock new paths, and gradually open up more of the map.

Co-op Experience - Up to four players can explore the world together, and players do not have to stay in the same area. Players can split up into different rooms and call each other for help when needed.
