How to play

• Enter on the title screen starts a game.
• Steer with the arrow keys or WASD — turns are buffered and taken at the next opening, like the arcade.
• Eat every pellet to clear the level; levels get faster. Power pellets — drawn as cherries — frighten the ghosts — they turn blue and dithered — so you can eat them for combo bonuses (200/400/800/1600); eaten ghosts race home as floating eyes.
• The board scales to your terminal. At larger sizes the actors are drawn as half-block sprites: Pac-Man is a circle whose mouth points where he's headed, ghosts get their classic domed-and-scalloped shape.
• You have 3 lives. Game over shows the top-5 high score table (persisted in SQLite via db/development.sqlite3).
• r/Enter restarts from the game over screen; q quits anywhere; ctrl+p opens the command palette.

The four ghosts have distinct brains: one chases you, one ambushes four tiles ahead, one wanders randomly, one patrols its corner. They alternate between scatter and chase on a timer.

Development

bundle exec rspec                      # full suite (game logic + controllers + views + integration)
CHARMING_ENV=test bundle exec charming db:migrate   # prepare the test database

Game rules live in plain Ruby under lib/pacman/arcade/ (no TTY needed to test them); the Charming app layer (controllers/views/components) is under app/. Live game state is held in memory per run — it intentionally does not survive a session's JSON serialization; only high scores persist.
