Did you know? This was my first Kirby game!
Kirby & the Amazing Mirror is a main-series Kirby game released for the Game Boy Advance on April 15th, 2004 in Japan, on July 2nd, 2004 in Europe, and on October 18th, 2004 in North America. It was produced by HAL Laboratory, developed by Flagship and Dimps, and published by Nintendo. Kirby & The Amazing Mirror looks and plays much like its predecessor, Kirby: Nightmare in Dream Land, but features an expansive and non-linear interconnected world with bosses that can be defeated in a number of different orders. The game also features four Kirbys of various color which can be played by up to four different players simultaneously, just like its predecessor. The different Kirbys can wander off in separate directions and assist each-other using their Cell Phones. The name of the game is a pun on "maze", as the game sports a labyrinth-like level layout different from other mainline Kirby games.
As it is based on Kirby: Nightmare in Dream Land, Kirby & The Amazing Mirror uses much of the same sprite-work, enemies, abilities, and mechanics as its predecessor. However, many additions and a few cuts were made to these categories. Included in the additions are new enemies like Chip, Roly-Poly, Golem, and others, some of which are quite complex in their ability to interact with Kirby. New abilities include Cupid, Missile, Mini, and a few returning favorites from Kirby Super Star such as Fighter and Cook. Due to the open nature of the game, most of the area bosses can be fought out of order, and aside from Kracko, they are all new (although some are heavily based on older bosses).
