- Awesome Music: The themes for Mustard Mountain, Radish Ruins, and Candy Constellation. Also, Dark Mind's second form theme.
- Olive Ocean as well.
- Best Boss Ever: Even it's considered That One Boss, the fight against Mega Titan is still extremely fun and hectic. Not to mention you're fighting a flying, four-armed, Rocket Punching mecha-knight called Mega Titan.
- Contested Sequel: This game has quite a bit of this going on due to the Metroidvania aspect of the game. While plenty of fans enjoy this take on a Kirby game, there are some fans who have criticized it for being overblown, confusing, poorly-designed and not meshing well the Kirby formula.
- Goddamned Bats: The Bronto Burts. In addition to them, there's the Sword and Heavy Knights (they move fast), Leap (they'll kiss you if you're not careful in the air, and you're helpless for a few seconds thanks to Kirby getting out a handkerchief and wiping the kiss off of his face), and Roly-Poly (He rolls down slopes and bumps into you if you're not careful). Also the Batty enemy.
- Droppy, who steals your ability and turns into the enemy you got it from. If it steals a boss-only ability like Hammer or Smash, it instead turns red and runs around randomly.
- Scrappy Mechanic: Some spots in the game require you to hold on to a specific ability until you reach a puzzle that requires it. If you take the wrong path, you'll have to return to the hub and retread the path, and if you lose your ability along the way, you'll have to find it again.
- One-way doors, which can make exploration and backtracking more tedious as you may have to leave the area and retrace your steps if you take the wrong door and it happens to be one-way.
- That One Boss:
- Mega Titan. His impenetrable armor (except against electric attacks) and fast attacks make for a frustrating fight.
- Returning from Nightmare in Dream Land, Phan Phan qualifies as That One Mid-boss. Between his pattern being randomized, moving insanely fast, and his attacks coming out quickly with little warning, he is by far the most annoying miniboss to fight.
- Box Boxer is also very annoying with his constant grabs, throws, and stunlocks.
- They Wasted a Perfectly Good Character: Although the game is centered around mirrors, Simirror (and, by extention, the Mirror ability) is nowhere to be seen.
- Unintentional Period Piece: The Kirbys can use large cellphones with antennae, which have been since displaced by smartphones.
