Create an engaging 2D Action Gun Game with multiple weapon types and heavy music integration.
Features to include:
- Gameplay: The player controls a shooter character using WASD/Arrow keys and aims/shoots using the Mouse Click.
- Gun Progression: A "Gun Game" mode where every 5 kills upgrades the player's weapon automatically (e.g., Pistol -> Shotgun -> SMG -> Rocket Launcher). Each gun must look different and have unique fire rates.
- Music Playlist System: Add a "Music Player" UI on the screen with a dropdown menu allowing players to choose from 4 different energetic background sound tracks (e.g., Electronic, Rock, Cyberpunk, Cinematic).
- Audio Effects: Unique, powerful sound effects for shooting each gun type and an explosion sound for the rocket launcher.
- Score System: Keep track of Level, Total Kills, and High Score with a beautiful Game Over screen.
