Honestly, most Kirby games follow a pretty predictable rhythm. You start on the left, you go to the right, you inhale a waddle dee, and eventually, you kill a god. It’s a comfort food formula that HAL Laboratory has perfected over decades. But then there’s 2004. Specifically, there’s Kirby and the Amazing Mirror.
If you grew up with a Game Boy Advance, this game probably confused the hell out of you. It wasn't just another platformer. It was a sprawling, interconnected labyrinth that felt more like Castlevania or Metroid than a typical pink puffball adventure. It was experimental. It was chaotic. And in 2026, looking back at the series' trajectory, it remains one of the most daring things Nintendo ever put its name on.
The Chaos of the Mirror World
The setup is classic Kirby weirdness. A Dark Meta Knight (not the cool one, the edgy mirror one) slices Kirby into four different-colored versions of himself. Suddenly, you aren't just one hero; you're a squad. But here’s the kicker: the game doesn't force you to stay together.
In most co-op games, you're tethered to your friends. In Kirby and the Amazing Mirror, your "partners" (whether AI or actual humans via a Link Cable) can literally just wander off to the other side of the world. You’ll be minding your business in Moonlight Mansion while Yellow Kirby is getting bodied by a boss in Mustard Mountain.
You actually have a cell phone—very 2004—to call them back to you. It uses battery power. If you’re low on juice, you’re on your own. This independence created a sense of scale that no other GBA game really matched. The Mirror World isn't a series of levels; it’s a massive, confusing, 9-area maze where you can technically fight the bosses in almost any order.

Why the Metroidvania Design Worked (And Why It Didn't)
Most people love a good map. This game’s map, though? It’s a nightmare.
It’s basically a grid of squares that doesn't tell you exactly where the doors go. You’ll spend hours trying to figure out how to reach that one blinking chest in Peppermint Palace, only to realize you needed to enter from a completely different zone like Cabbage Cavern. It’s frustrating. It’s also incredibly rewarding when you finally stumble onto a shortcut.
The Ability Gatekeeping
Like any good Metroidvania, progress is tied to your powers. You see a heavy block? You need Stone or Hammer. A high platform? Maybe Cupid or Hi-Jump (which was actually cut from the final game's regular roster but exists in the code). The "Smash" ability, which gives Kirby his moveset from Super Smash Bros. Melee, is the ultimate prize here. It’s hidden, it’s powerful, and it makes you feel like a total badass in a world of colorful fluff.
A Collaboration of Giants
Part of why this game feels so "off" compared to other titles is the development pedigree. It wasn't just HAL. It was a joint effort with Flagship (a Capcom subsidiary) and Dimps. Flagship was the studio behind the Legend of Zelda Oracle games and The Minish Cap. You can feel that Zelda-style "world as a puzzle" DNA everywhere in the Mirror World's design.

The Multiplayer Hurdle
Back in the day, playing this the "right" way was a logistical nightmare. You needed:
- Four Game Boy Advances.
- Four copies of the game.
- Three Link Cables.
- Three friends who didn't mind Kirby’s "kiddie" aesthetic.
If you played alone, the AI Kirbys were... let's say, "special." They would frequently inhale the exact ability you needed or jump into pits for no reason. But when you actually got four humans together? It was pure, unadulterated madness. You could split up to find switches, share food to heal, and jump into boss fights halfway through to save a friend.
The Nintendo Switch Online version has fixed some of this by adding online play, but there’s still something about that original hardware lag and the physical mess of cables that defined the experience.
Secrets and the 100% Grind
If you're looking to 100% this thing, God help you. Unlike modern games that hold your hand, Kirby and the Amazing Mirror hides its treasures with zero mercy.

- Spray Paint: This was the peak of GBA customization. Finding different colors to paint Kirby (like Chocolate or Grape) was the main reason to explore every nook and cranny.
- The World Map: You don't even start with a full map. You have to find the map for each individual area, usually guarded by a mid-boss or hidden behind a clever environmental puzzle.
- Master Sword: After you collect the eight mirror shards and defeat Dark Meta Knight, you get the Master Sword. It’s the best ability in the game, capable of cutting ropes, smashing blocks, and lighting fuses. It’s basically the "Easy Mode" button, but you have to earn it.
The final boss, Dark Mind, is a multi-phase marathon that feels more like a bullet hell shooter than a platformer. It’s a sharp spike in difficulty that catches a lot of casual players off guard.
How to Play It Right Today
If you’re diving back in, don't try to play it like a linear game. You will get lost. That's the point.
Treat the hub world—the Rainbow Route—as your home base. Every time you find a big switch in a new area, it opens a permanent portal back to the hub. Your goal isn't just to "beat" the game; it's to connect the dots on the map until the whole Mirror World is accessible.
Quick Tips for the Modern Player:
- Don't ignore the Mini ability. It seems useless because you can't attack, but it's the only way to reach about 10% of the game's secrets.
- Save your battery. Don't call the other Kirbys unless you’re actually at a boss. The AI is more likely to steal your health than help you in a regular room.
- Check the walls. This game loves "fake" walls that look solid but can be walked through. If a room feels like a dead end, it probably isn't.
Kirby and the Amazing Mirror is a weird relic from an era where Nintendo was willing to break its own rules. It’s messy, it’s confusing, and it’s occasionally annoying. But it’s also one of the most unique experiences in the entire 2D platforming genre. Whether you’re playing on original hardware or a modern emulator, it’s a trip worth taking just to see what happens when Kirby stops following the path and starts wandering.
Start your run by focusing on Area 2 (Moonlight Mansion) to get the hang of the mechanics. Once you defeat King Golem, the world really opens up—just try not to lose your mind when you realize you've been going in circles for twenty minutes.
