3d FPS SANDBOX GAME

This game is a fast-paced 3D FPS survival arena with arcade progression.

• You control the player in first-person with WASD to move, mouse to look, and Spacebar to jump.
• You use right-click to fire. Shots feel punchy with visual trail/muzzle effects.
• The arena includes interactive explosive barrels. Shooting them triggers colorful combustion blasts that can damage nearby enemies.
• Enemies use simple AI behavior: they seek you, close distance, and attack when near.
• You have a health system. If health reaches 0, the run ends in a Game Over screen with a Try Again button.
• A score/kill loop drives progression:

1. Kills increase your score.
2. Every few kills, your level rises.
3. Higher levels make enemies stronger (more health, speed, and damage).

• A high score history stores the top two runs (1st and 2nd) so you can compete against your best attempts.

Overall, it plays like a compact FPS horde game: survive, chain explosions, climb levels, and beat your top scores.
