YMMV / Kirby's Adventure

  • Even Better Sequel: Kirby's Dream Land was a fun game, but very short and rather vanilla in gameplay. This sequel considerably improved on it with more ambitious level design, some of the best graphics the NES could churn out, the series' iconic Power Copying, and was the debut of the fan-favourite character Meta Knight.
  • Game-Breaker:
    • Spark and Freeze. They both create a force field around Kirby, allowing players to quickly shield themselves from danger when the situation calls for it. Try them against bosses as well. You may be shocked by the damage they can do. It was also cool of the level designers to have both of these abilities accessed relatively early on in the game.
    • The UFO ability gives Kirby the ability to fly and hover around at his own pace (provided there are no ladders. In addition, the UFO has 4 attacks, depending on how long each button is pressed. Pressing B is a copy of the Beam ability, holding B for a short time is a copy of the Laser ability, holding B for a medium amount of time makes the Laser stronger, and holding B for a long amount of time increases the power and gives it the ability to go through walls. Its main drawback is that it only lasts for one level, but can be circumvented with a glitch below. If you use that glitch, the game becomes trivial.
  • Good Bad Bugs:
    • 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 level. 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 level and in the hub areas.
    • 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 Mike ability from then on, even if you get your power knocked out of you by getting hit. This bug only exists in the NES version.
  • Growing the Beard: 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.
  • Polished Port: The 3DS remake eliminates the lag and the slowdown present in the original NES game, while still keeping the original 8-bit visuals (and rotating Butter Buildings).
  • That One Boss:
    • Mr. Shine & Mr. Bright also qualify in the eyes of some players, since it can often be difficult to deal with the one on the ground and the one in the air at the same time.
    • Meta Knight may very well be the hardest boss in the game - for starters, the Sword ability is forced onto the player, preventing any alternatives from being used (and unlike Kirby Super Star, picking up the Sword is required to even start the fight). Secondly, Meta Knight moves very erratically, making contact damage almost guaranteed. Finally, he is invincible unless attacked at specific times- namely, while in the air or from behind- and even if you do get behind him, he'll quickly turn around and more often than not hit you back. The difficulty was dramatically decreased in the GBA remake, where simple Button Mashing will nearly always win the fight due to Meta Knight's slower reflexes and the range of the sword.
    • King Dedede becomes this 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 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 do minimal damage to him as well. note 
  • They Changed It, Now It Sucks: Nightmare in Dream Land is markedly easier than Kirby's Adventure...and missed the point of some of the original level design, most notably the rotating tower segments from Butter Building being removed for no apparent reason. Fans were not pleased.
  • They Wasted a Perfectly Good Character: Nightmare, who doesn't even get a mention, let alone an appearance, until right at the end.
  • Visual Effects of Awesome: The rotating parallax towers in Butter Building. Running around them even affects nearby enemies. Many people felt disappointed when this set-piece was dropped in the GBA remake in favor of a less impressive mist effect.
