Built with good company.

Our characters and worlds

Zubboo’s character family, game artwork and environments were developed for this project using AI-assisted image generation, custom layouts and rendering code. Generated images are adapted into playable scenes; the games are not videos or screenshots of another creator’s game.

Our implementations, level layouts, puzzle collections and interface copy are developed for Zubboo. Familiar genre mechanics have a longer history: Sweet Stack uses the sliding-and-merging tradition popularised by Gabriele Cirulli’s 2048, with an independent rules implementation, cupcake collection and its own daily challenge.
