About This Game

Discover the rules of color and begin a journey to reclaim the lost colors.


YellowJacket
is a 2D platforming adventure game set in a world that has lost its colors. Recover the scattered jackets and bring color back to the world.


Fun points

  • Color is the rule of the game. Players can acquire new colors and freely switch between them. Depending on the currently selected color, the paths you can traverse and the objects you can interact with change, allowing you to explore the same stage in new ways.

  • Easy to learn, hard to master. Anyone can easily start with just movement and jumping, but the gameplay changes significantly depending on when and how you use colors.

  • An exploration to find hidden paths. As you acquire new colors, previously inaccessible paths open up. Discover hidden areas and various gimmicks to experience the fun of exploration.

  • Charming pixel art. We have expressed Yellow Jacket's unique world through vivid colors and cute pixel graphics.

🎮 User Gameplay Reviews 

"It was really refreshing that the path changed just by changing the color."

The controls are simple, but as you clear stages, the depth of the puzzles increases, making you want to keep challenging yourself.

The moderate difficulty and quick retries were appealing enough to make me want to try again.

The pixel art and colors were really cute, and the music blended well, making the entire gameplay enjoyable.
