Tumble: A Cozy Dice Roguelite

Tumble's visual art (character and charm illustrations, backdrops, item sprites, and store capsule art) was generated with Google's Gemini image models and then selected, cropped, retouched, colour-matched and in many cases regenerated by hand against a fixed reference style until it fit the game. Music and sound effects were generated with Suno under a commercial licence, then cut, mixed and placed by hand.

The game's design, rules, balance, and code are not generated content. Every mechanic, number and line of player-facing text was written, tested and revised by the developer, including through automated balance simulation and four rounds of human playtesting.

No content is generated live during play. Nothing in Tumble is produced at runtime by an AI model; the game runs entirely offline with no model calls of any kind.
