Ember is an open-source, local workspace for building browser games with Muse. Start with an empty project and describe the game you want to make. Muse proposes a playable build, and Ember lets you inspect the files and play the proposal in your browser before you approve it.
- Project scope and approvals. Define the game’s features, art direction, and completion criteria. Ember uses contracts to limit which files a task can write and applies the exact changes you approve.
- Gameplay checks. Save repeatable tests that press keys, click buttons, or tap touch controls and check visible outcomes such as a score or win screen. Run the same test against the current game and a proposed build to see what the change fixes or breaks.
- Playtest and repair. Record a bug while playing, give Muse the reproduction steps, and review the proposed fix alongside the current game.
- Game assets. Preview sprite animations and tiled terrain, and validate supported Blender props as GLB files in a playable browser scene. Review and accept assets before adding them to the approved game.
- Version history and export. Revisit approved builds, review a restore, or export a playable ZIP with a handoff report that records the approved scope, gameplay results, and open findings.
