+The code in this project (The sources have moved to repository [pacman-javafx](https://github.com/armin-reichert/pacman-javafx/tree/main/pacman-core) is more "to the point" than the one in my other [state-machine focussed implementation](https://github.com/armin-reichert/pacman).
 
 The implementation follows the Model-View-Controller design pattern:
-- The game controller is a [finite-state machine](https://github.com/armin-reichert/pacman-javafx/pacman-core/src/main/java/de/amr/games/pacman/lib/Fsm.java) with states
-  -  INTRO, CREDIT, READY, HUNTING, LEVEL_STARTING, LEVEL_COMPLETE, PACMAN_DYING, GHOST_DYING, GAME_OVER and INTERMISSION. (See [GameState](https://github.com/armin-reichert/pacman-javafx/pacman-core/src/main/java/de/amr/games/pacman/controller/GameState.java))
-- User interfaces can be attached to the model/controller layer using a [game event listener](https://github.com/armin-reichert/pacman-javafx/pacman-core/src/main/java/de/amr/games/pacman/event/GameEventListener.java) interface.
