You probably remember the DS for Nintendogs or Brain Age. Maybe you spent hours scribbling in Phantom Hourglass. But honestly, there’s this weird, rhythmic, slightly frustrating, and incredibly satisfying gem called Donkey Kong: Jungle Climber that most people just sort of... forgot about. It’s a sequel, technically. It followed DK: King of Swing on the Game Boy Advance, but it polished that weird "peg-swinging" mechanic into something that actually felt like a Triple-A Nintendo experience.
It’s bizarre.
Instead of running and jumping like a normal ape, you’re basically a sentient pendulum. You use the L and R buttons to grab pegs. That’s it. Well, mostly. It sounds simple, but once you’re three worlds in and trying to dodge a Flaming Klinger while timing a lunge across a bottomless pit, you realize it’s secretly one of the most mechanically dense games on the handheld.
The Mechanics of the Swing
Standard platformers are about horizontal momentum. Donkey Kong: Jungle Climber throws that out the window. Since you use L to grab with the left hand and R for the right, the game becomes a literal physical rhythm. If you hold L, DK spins counter-clockwise. Hold R, he spins clockwise. Let go at the peak of the arc, and you launch.
It feels more like rock climbing than platforming.
Paon, the developer behind this (and the Wii's DK Barrel Blast), really leaned into the dual-screen setup. Unlike many DS games that used the bottom screen for a map or a clunky inventory, Jungle Climber treated both screens as one giant vertical playground. You’d swing off the bottom screen and soar into the top one. It gave the game a sense of scale that felt massive back in 2007.
The physics are heavy. DK has weight. When you’re swinging, you feel the centrifugal force pulling at the "muscles" of the DS triggers. It’s a tactile experience that most modern mobile "one-tap" games try to replicate but usually fail because they lack this specific, chunky feedback.

Why the Banana Spaceship Actually Works
The plot is... well, it’s a Donkey Kong game. DK, Diddy, and the gang are on vacation. They see a giant banana in the sky. It turns out to be a spaceship. Enter the Xananab, an alien banana who needs help getting Crystal Bananas back from King Krule.
It's absurd.
But this weird sci-fi pivot allowed Paon to move away from just "jungle levels." You end up in glass factories, icy peaks, and literal outer space. The Crystal Bananas aren’t just collectibles; they grant DK temporary powers. We’re talking giant-sized invincibility or fire-breathing. It breaks up the "grab, spin, let go" loop just enough to keep you from getting bored.
The Diddy Kong Factor
Don’t play this game without Diddy. Seriously.
In Donkey Kong: Jungle Climber, Diddy Kong acts as a power-up. You find him in barrels, and he hitches a ride on your back. This opens up the "double-jump" or lunge mechanic. When you have Diddy, you can launch him forward to hit distant enemies or grab out-of-reach items.
There are also specific sub-weapons. Diddy can hold a hammer to smash through rock walls or use a blowgun. It adds a layer of "Metroidvania-lite" to the levels. You’ll see a cracked block and realize you need to come back once you’ve found Diddy in that specific stage. It’s a smart way to encourage exploration in what is otherwise a very linear "get to the top" experience.

Technical Prowess on the DS
Visually, this game was a powerhouse. It used pre-rendered 3D sprites, much like the original Donkey Kong Country on the SNES, but with a much higher color palette and smoother animations.
The transition between the screens is seamless. There’s a small "blind spot" caused by the physical gap between the DS screens, and the game actually accounts for this. If an enemy is in the "gap," you can’t see them, but the trajectory of your jump remains mathematically consistent. It’s a detail most developers ignored, but Paon nailed it.
What Most People Get Wrong About the Difficulty
A lot of reviews at the time called the game "fiddly."
That’s a polite way of saying they kept falling into spikes.
The learning curve in Donkey Kong: Jungle Climber isn't about reflexes; it's about internalizing the circle. If you try to play it fast, you will die. Every time. The game demands that you wait for the rotation. It’s a test of patience.
The boss fights are where this really peaks. You aren't just jumping on King Krule's head. You’re navigating complex arenas where the boss might be destroying the very pegs you need to survive. The final encounter is notorious for being a genuine "Nintendo Hard" moment. You have to manage your grip, your lunge, and your Crystal Banana power-ups all while the screen is scrolling or the floor is disappearing.

The Legacy of the "King of Swing" Style
Why didn't we get more of these?
Honestly, the DS hardware was the perfect storm for this mechanic. The L and R buttons were chunky and satisfying. Trying to play this on a modern console with analog triggers like the PS5 or Xbox would feel mushy. The DS triggers were digital—on or off. That precision is what made the swinging work.
It's a shame. Jungle Climber represents a time when Nintendo was willing to let weird, experimental B-tier projects have a massive budget and a polished finish. It wasn't just a spin-off; it was a full-throated reimagining of what a Donkey Kong game could be.
Essential Tips for Modern Players
If you’re picking this up on original hardware or through other means today, keep these things in mind:
- Calibrate your triggers. If your L or R buttons are "crunchy" or unresponsive, this game is literally unplayable. You need frame-perfect releases.
- The 100-Banana Rule. Collecting 100 bananas gives you an extra life, obviously, but in this game, they are placed to guide your trajectory. If a line of bananas curves to the left, that’s exactly where you should release your grip. Follow the fruit.
- Don't ignore the oil drums. The mini-games are actually fun. They help you master the "lunge" mechanic which is vital for the later space levels.
- Check the bottom screen. Hidden paths are often tucked away in the "dirt" sections at the very bottom of the map that you’d normally ignore once you start climbing.
Actionable Steps for Completionists
To truly beat Donkey Kong: Jungle Climber, you aren't just looking for the end credits. You're hunting for the DK Coins and the secret map pieces.
- Revisit World 1 with Diddy: Once you get used to the hammer mechanic, go back. There are sections in the early jungle that are impossible to reach without him.
- Master the "Booster" Jump: Practice jumping from a moving peg to a stationary one. The momentum carries over, and it's the only way to reach the highest "S" rank medals in the bonus stages.
- Watch the Shadow: DK casts a tiny shadow on the background. Use this to judge your "depth" when trying to land on narrow platforms or single-point pegs.
The game is a masterclass in singular mechanic design. It takes one idea—grabbing with two hands—and stretches it across an entire galaxy of content. It’s weird, it’s colorful, and it’s arguably the most unique platformer in the entire Kong library.
