-# TODO
-
-**1. Core Gameplay Loop & State Management:**
-
-*   ~~**Player Lives:**~~ **(DONE)**
-    *   ~~Add a `PlayerLives` resource (e.g., starting with 3).~~
-    *   ~~Modify `check_player_enemy_collisions`: Instead of just printing, decrement the lives count.~~
-    *   ~~Implement player destruction (despawn the player sprite) and respawn logic (maybe after a short delay, with temporary invincibility).~~
-*   ~~**Game Over State:**~~ **(DONE)**
-    *   ~~Use Bevy's `States` (e.g., `Playing`, `GameOver`).~~
-    *   ~~Transition to `GameOver` when `PlayerLives` reaches zero.~~
-    *   ~~In the `GameOver` state: stop enemy spawning, stop player controls, display a "Game Over" message (using `bevy_ui`), potentially offer a restart option.~~
-*   ~~**Scoring:**~~ **(DONE)**
-    *   ~~Add a `Score` resource.~~
-    *   ~~Increment the score in `check_bullet_collisions` when an enemy is hit.~~
-    *   Consider different point values for different enemy types or hitting enemies during dives later.
-*   ~~**Levels/Stages:**~~ **(DONE)**
-    *   ~~Add a `CurrentStage` resource.~~
-    *   ~~Define criteria for clearing a stage (e.g., destroying all enemies in a wave/formation).~~
-    *   ~~Implement logic to advance to the next stage, potentially increasing difficulty (enemy speed, firing rate, different formations).~~
-
-**2. Enemy Behavior - Formations & Attack Patterns:**
-
-*   **Enemy Formations:** This is a core Galaga feature.
-    *   ~~Define target positions for the enemy formation on screen.~~ **(DONE)**
-    *   ~~Give enemies an `Entering` state/component: They fly onto the screen following predefined paths (curves, waypoints).~~ **(DONE - Basic linear path implemented)**
-    *   Give enemies a `Formation` state/component: Once they reach their target position, they stop and hold formation. **(DONE - Stop implemented by removing FormationTarget)**
-*   **Enemy Attack Dives:**
-    *   ~~Give enemies an `Attacking` state/component.~~ **(DONE)**
-    *   ~~Periodically trigger enemies in the formation to switch to the `Attacking` state.~~ **(DONE - Random selection after formation complete)**
-    *   ~~Define attack paths (swooping dives towards the player area).~~ **(DONE - Basic swoop towards center implemented)**
-    *   ~~Make enemies fire bullets (downwards or towards the player) during their dives.~~ **(DONE - Downward)**
-    *   After an attack dive, enemies could return to their formation position or fly off-screen. **(Fly off-screen implemented)**
-*   **Enemy Variety:**
-    *   ~~Introduce different types of enemies (e.g., using different components or an enum).~~ **(DONE - Added EnemyType enum and field)**
-    *   ~~Assign different behaviors, point values, and maybe sprites to each type.~~ **(DONE - Behaviors, points & color based on type)**
-
-**3. Advanced Galaga Mechanics:**
-
-*   **Boss Galaga & Capture Beam:**
-    *   ~~Create a "Boss" enemy type.~~ **(DONE - Added to Enum, handled in matches)**
-    *   Implement the tractor beam attack (visual effect, player capture logic).
-    *   Player needs a `Captured` state.
-    *   Logic for the Boss to return captured ships to the formation.
-*   **Dual Fighter (Rescuing Captured Ship):**
-    *   Allow the player to shoot a Boss Galaga attempting to capture or one holding a captured ship.
-    *   Implement the logic to free the captured ship.
-    *   Implement the dual fighter mode (controlling two ships, firing two bullets). This involves significant changes to player control and shooting systems.
-*   **Challenging Stages:**
-    *   Implement a special stage type (e.g., every few levels).
-    *   Enemies fly in intricate patterns without shooting.
-    *   Award bonus points for destroying all enemies in the stage.
-
-**4. Polish and User Interface:**
-
-*   **Visuals:**
-    *   Replace placeholder shapes with actual sprites using `SpriteBundle` or `SpriteSheetBundle`. Create distinct looks for the player, different enemy types, bullets.
-    *   Add explosion effects/animations when enemies or the player are destroyed.
-    *   Implement a scrolling starfield background for a more classic space feel.
-*   **Audio:**
-    *   Integrate `bevy_audio`.
-    *   Add sound effects for player shooting, enemy firing, explosions, player death, capturing, etc.
-    *   Add background music that might change per stage or state (e.g., main gameplay vs. challenging stage).
-*   **UI:**
-    *   Use `bevy_ui` to display the current Score, Lives remaining, and Stage number on screen during gameplay.
-    *   Display High Score?
-    *   Create a Start Menu state.
-
-Starting with the Core Gameplay Loop (Lives, Game Over, Score, basic Stages) and then moving onto Enemy Formations and Attack Patterns would likely provide the biggest steps towards a Galaga feel.

-Use Conventional Commit format.
-Avoid overly verbose descriptions or unnecessary details.
-Start with a short sentence in imperative form, no more than 50 characters long.
-Then leave an empty line and continue with a more detailed explanation.
-Write only one sentence for the first part, and two or three sentences at most for the detailed explanation.
-Keep message as short as possible.
-Use bullet points for multiple changes.
