OhMyGame is an open-source desktop app for making games with AI. Describe a game, and an agent writes the design doc, makes the art, builds the game, plays it to check it works, and publishes it to a link anyone can open.
OhMyGame is in beta. It runs on macOS (Apple silicon) and Windows (x64), and its source is on GitHub under the Apache-2.0 license.
What’s in the app
- Agent. It writes the code and runs the game in a live preview. It then plays the game in a window you can watch, real-time canvas and WebGL games included. When it finds a problem, it tries a fix and plays again. Along the way it can generate images, video, 3D models and audio, search the web, and use MCP servers and plugins.
- Canvas. Design docs, images, video, 3D models and audio sit side by side on one board. Nodes use each other as references, so one character sketch can become more art, a video, or a rigged 3D model. Results go into an Asset Library your games can use.
- Publish. Sign in and publish, and your game gets a link that plays in the browser. Republishing updates the same link, and published games are listed in the Community.
- Plugins. The agent can work in Godot, Unity, Unreal Engine, Cocos Creator, Blender, Aseprite and Tiled. Plugins also ship your game to TapTap, WeChat Mini Games and Douyin Mini Games.
