Rainbow Billy: The Curse of the Leviathan is an adventure game developed by ManaVoid Entertainment. It is available on Nintendo Switch and comes with a full license. The game is set in a world that is cursed into monochromatic chaos by the Mighty Leviathan. As the player, you get to explore this world, solve intricate color puzzles and unlock new areas to explore. The game also lets you bring back the lost colors of the world by confronting colorless creatures and befriend strange creatures you encounter in your journey to create your own unique team.

The game has an aesthetic that combines the art styles of cartoons from the 1930s and anime, bringing the world to life in a unique way. It also has over 60 creatures that you can collect, friends and foes alike, to create your own team and conquer the seas. The in-house shader used in the game brings back, color by color, any visual asset in 2D or 3D. The game also uses colors in innovative ways in puzzles and combat. And of course, no great game is complete without a fishing mini-game!
