YMMV / Kirby's Halloween Adventure

• Big-Lipped Alligator Moment: Compared to the game's usual interconnected levels, Stage 3 of Mount Mist is sandwiched between a volcanic passage and a desert on the wild west. Mount Mist 3 is a Ninja Hideout in the middle of a lush spring blossomed forest, and it's not acknowledged on the slightest on the level following it.
  • Official artwork tries to make sense of it as the forest takes place in the bottom of the mountain, with the wooden logs the train of the following level being timber from this forest, but in-game it's a lot more sudden compared to the rest of the game's worlds.
• Goddamned Bats: Invoked, as the homing Bronto Burt AI was seemed to be potentially annoying, and this game exploits that reaction to induce more adrenaline to the player (getting chased by a ghost or a bat). Most deliberate example is on the Mumbies enemy in the pyramid level, placed on specific spots as they will respawn whenever you continue passing through any of those tight corridors.
• It's the Same, Now It Sucks!: The main criticism behind the original 1.1 patch, as the level design doesn't change enough to warrant a new playthrough besides enemy design curiosity.
  • Hades Harbor proved to be the least popular of the 7 worlds in the 1.2/1.3 patches, mostly for some levels staying largely the same or too unchanged. This criticism actually lead to the creation of the 1.4 patch to finally redo every repeated level from the original to avert this.
• Just Here for Godzilla: Because the earliest patches were relatively vanilla, most that played the game did so to look at the Reference Overdosed ability icons.
• Padding: The mid-boss tower in stages 1.2 and 1.3 really bloated the playtime with its custom layouts and its sections between mid-boss transitions. It wound up removed in 1.4.
• That One Boss: The twin Bonkersteins at the very end of Mount Mist's sixth stage, especially on original hardware where their presence will lag the game much further. It was trimmed down to just one in 1.4 cause of this.
  • The twin Fire Ligers in Stage 6 of Hades Harbor. Fighting them on an incredibly cramped room and fighting them both with desynced AI was a huge roadblock behind the battle with Meta Knight. It was also trimmed down to just one in 1.4 due to this, but Twin Fire Ligers are fought (on a much more spacious stage) on the newly added Stage 3 of Ghostly Graves.
• Underused Game Mechanic: Despite getting several levels themed after volcanoes, lava tiles rarely get to present a legitimate challenge to the player as they're usually surrounded by very safe platforms and appear very rarely or more as decoration.
