In 2002, a remake titled Kirby: Nightmare in Dream Land was released for the Game Boy Advance. The new version has, in addition to new visuals and sound, different minigames, a multiplayer mode, and other new features. However, it also had some criticism for the omission of certain materials that pushed the NES to the limit, and replaced by what is often considered lazy for the Game Boy Advance. For instance, the rotating pseudo-3D towers in Butter Building were removed. In addition, the difficulty is significantly lower. A demo of the game is available in "Super Smash Bros. Brawl". In 2011, a re-release of "Kirby's Adventure" named "3D Classics: Kirby's Adventure" was released for the Nintendo 3DS. It is a 3D version of the game.
