About this game
Yellow is a WebGL puzzle game that can be played directly in the browser, with a fully 3D scene built using Three.js. Players lay out a connected path toward the starry sky among stone pillars of varying heights: tap a stone pillar, and it rises or lowers together with the four neighboring pillars above, below, left, and right. You must connect the start and goal within a limited number of moves and find the route with the fewest moves. The game has 60 levels divided into 5 chapters; each level has an optimal move count verified by a programmatic solver. The first level has an interactive tutorial, and after that contextual hint cards are provided. Star progress is stored in the browser; accumulating more than 280 stars unlocks a hidden final chapter. It also includes character animations and ending music. The project is a purely static website, written in vanilla JavaScript and Three.js, and is provided under the MIT license.
