 ## Demo app
 
-`lightkeeper` is the current demo application. It creates an SDL window, initializes the Destrum app, loads assets, sets up a scene, renders meshes, skyboxes, and a skinned animated character.
+`lightkeeper` is the current game application. It launches **Star Catcher**, a small playable loop built from the engine's scene and rendering systems. Move the blue catcher with `A`/`D` or the arrow keys, catch orange stars, and press `R` to restart after three misses. Press `Escape` to quit.
