Describe a change and the assistant rebuilds the game turn by turn, showing the credits each turn used.
Create character sprites, sprite animations, and 3D models for a scene without leaving the editor.
Add background music, sound effects, and 360° skyboxes so the game feels finished rather than a prototype.
Paid plans let you download the project code and export a Windows build you can publish on Steam.
Turn a weekend idea into a shareable browser game without learning an engine or writing any code.
Prototype a mechanic quickly, then download the project code on a paid plan and keep building.
Students can build and share a game from one prompt, so class time goes into design ideas.
Quick start
Describe the smallest playable loop first, such as move, collect, and score, and confirm it runs in the browser before adding art or extra systems.
Use the Rosie assistant for changes to the game you already have rather than for regenerating from a new idea, so each iteration keeps the working parts.
Generate sprites only after the mechanics feel right: art assets are the most expensive thing to redo when the design changes.
Pro tip
Treat the first playable version as a throwaway prototype. Mechanics that feel wrong in a plain prototype will still feel wrong with better art, so fix the loop before spending on 3D models or music. Download the project code once the prototype is fun: the export is what lets you continue in a real engine and keeps you from rebuilding the game if the platform changes.
