Playable preview
Playable PC game preview
A first playable version should show what Stage Engine built, what you can play, and what should feel better next.

Example scenario
This starter/example surface is a third-person adventure room: a character can move through the space, the camera follows the action, and the creator can judge what the next room or goal should feel like.
What Stage Engine can change
Stage Engine can work from the starter shape, read movement, camera, level layout, collectible placement, and feedback timing, then make the next playable pass more specific.
Known limit
This is not a finished commercial game or a user outcome claim. It is a concrete starting surface that shows what a creator can play, review, and ask Stage Engine to improve next.
