History YMMV / KirbysAdventure

** For some Copy Abilities (namely Sword, Parasol, Hammer and UFO), it is possible to keep them forever by discarding the ability while pausing the game and exiting a stage. The game will treat Kirby as if he has no power, while he still has it. This means getting hit will not cause Kirby to lose the ability (discarding the ability or dying will, however, and reswallowing the star doesn't restore the ability), and one-round abilities can last until you die or you give it up). This means that UFO Kirby can be used in every stage and in the hub areas.

** Meta Knightmare in ''Nightmare in Dream Land''. Like with Extra Game, you start with two lives and get three hit points, but unlike the GBA remake's Extra Game, you can't save your game. Meta Knight gets six sword based attacks that can solve all puzzles and he moves faster, but he can't copy abilities and is much heavier than Kirby.

** Stage 5-6's switch is hidden at the very end and requires Hammer to break the blocks obstructing it. Problem is, it's quite a long stage and Hammer can't be found there, so you have to acquire it somewhere else and get through to the switch's hiding spot without losing it. Possible case of GuideDangIt! in the original, where the blocks look like the surrounding terrain (albeit colored differently) and don't indicate which ability breaks through, the remake changes them to generic metal blocks to be more obvious.

** Some fans aren't fond of the new art direction for portraying the environments very differently to their original incarnations. Most notably, Butter Building on the NES was a grand, stately building but in the remake it's a decrepit ruin.

* GrowingTheBeard: This was the first ''Kirby'' game to introduce Copy Abilities and a save feature, and it introduced other iconic series hallmarks, like fan-favorite Meta Knight.

** Heavy Mole is an [[GetBackHereBoss autoscrolling boss]] that keeps destroying the earth in front of it, meaning that the player has to constantly adapt to the perpetually changing environment while avoiding getting crushed by the scrolling walls or falling into a pit. Heavy Mole's missiles offer two copy abilities: Hammer, which brings the double-edged sword of tearing the dirt that forms the arena, and [[JokeItem Sleep]], which temporarily immobilizes Kirby and has a high risk of [[PoisonMushroom screwing the player over]]. There are cosmetic differences between the two types of missiles, but they're somewhat subtle and hard to notice during the rush to defeat the boss.

** [[DiscOneFinalBoss King Dedede]] becomes this [[AdaptationalBadass in the GBA remake]]. While he's a bit quicker in the NES version, he's bigger here despite the screen's smaller resolution -- so both he and his attacks (especially his [[VacuumMouth inhale]]) become much harder to avoid -- and his characteristic ''"flinching-when-hit"'' does not stop his attacks or momentum when he jumps. With that, you can very well end up hitting him, only for him to fall on you or stomp you with his Hammer to cause damage like nothing happened. Oh, and most of the Copy Abilities [[DamageSpongeBoss do minimal damage to him as well]]. [[note]]On the bright side though, you do get some [[https://www.youtube.com/watch?v=NzijAhol4XI awesome music]] when you fight him in the GBA remake -- a rendition of the "Fountain of Dreams" theme from ''VideoGame/SuperSmashBros Melee'', compared to the NES version's use of the standard boss theme as opposed to a unique composition or the Mt. Dedede theme (EarlyInstallmentWeirdness may play into this a bit, as at the time it was simply a theme for the ''VideoGame/KirbysDreamLand'' stage rather than being a distinct motif for King Dedede, kinda like how the castle theme in ''VideoGame/SuperMarioBros1'' never actually became a motif for Bowser).[[/note]]

* SeinfeldIsUnfunny: The game wasn't just innovative for the overall ''Kirby'' franchise, but it also pushed the upper limits of the NES; it features many large and detailed sprites, great use of color, a catchy and varied soundtrack, lush animated backgrounds (including the famous rotating towers in Butter Building), and extra features such as save files and a BossRush mode. In fact, much of this was uncommon even on 16-bit systems of the time; nowadays, it can be easy to take all of this for granted and see ''Adventure'' as a typical NES game.

* AntiClimaxBoss: [[spoiler:Nightmare's second phase can be ridiculously easy once you nail down his attack patterns, which are mostly predictable and easy to dodge]].

* BestLevelEver:

** The original game has otherwise-pointless floating platforms connected to background elements like hills to add extra atmosphere. The remake apparently [[http://imgur.com/a/suA3d missed the point of of this level design and removed the background elements,]] resulting in floating platforms that are now just flat-out pointless.

** If you use your last charge on a Mike ability to deal the finishing blow to Paint Roller while on the spot where the Star Rod piece spawns, you collect the piece and the game skips the check on whether your power has run out or not. This allows you near-infinite uses of the [[MakeMeWannaShout Mike ability]] from then on, even if you get your power knocked out of you by getting hit. This is also possible on a stage with a switch or in the Kracko battle. This bug only exists in the NES version.

* RemadeAndImproved: Although some of the changes made have been criticized by fans of the original (such as the removal of the rotating Butter Building towers), a substantial camp of fans consider the GBA remake, ''Nightmare in Dream Land'', largely superior to the NES original. It boasts updated and gorgeous visuals, tighter controls, lacks the lag and slowdown featured in the original, new mini games and an entirely new mode in which you play through most of the campaign as Meta Knight. It even adds the Copy Ability hats from ''VideoGame/KirbySuperStar''.
