Particle System: Visual Effects for Enemy Deaths

[vivinarya]

Problem: Visuals upon enemy death are plain; we want juicier effects.

Task:

• Implement a Particle class in script.js.
• When an enemy is destroyed, spawn 20 small particles that scatter outward and fade out according to basic physics (e.g., velocity, friction, alpha).

Acceptance Criteria:

• Destroyed enemies generate 20 particles each.
• Particles scatter, move, and fade out smoothly.
• All code restricted to script.js.
