Kirby - Nightmare in Dream Land
For the most part, the game plays similar to its original NES incarnation. The game is a platformer; the point is to get to the end of the current level through walking and jumping over obstacles and defeating enemies, but can also fly indefinitely. Due to his unique ability to inflate, Kirby can jump an infinite amount of times, although he cannot leave the screen from any direction except the bottom. Kirby can inhale his enemies and copy their abilities for new, stronger attacks. This is one of the staples of the series, being an included feature in nearly every Kirby game since Kirby's Adventure.
Some new additions to the remake include 4-player support, 32-bit graphics, a decrease in difficulty, hats for most abilities, the three main minigames from the original Kirby's Adventure being replaced by new ones, certain enemies from the original being replaced with new ones, and certain changes to certain levels. In addition, there are changes in the mechanics of certain copy abilities (Needle Kirby's spikes do not retract automatically, Wheel Kirby can drive on water, Backdrop Kirby dash-and-grabs enemies instead of inhale-and-grabbing them).
Meta Knight, Kirby's rival, also makes his debut playable appearance in the sub-game "Meta Nightmare!" after completing Extra Mode with Kirby. Meta-Knightmare is like playing Extra Mode but as Meta Knight. You have 3 health bars and no ability to save progress. Meta-Knight's sword can be used on all puzzles.
