Particle simulation on GPU using compute shaders in Unity

Used this article but simplified it to 2D circles, skipped torque calculations and used compute shaders instead of vertex + fragment + depth test

No optimizations done, stats in editor on my laptop RTX 3060:

• 250k particles - 250+ FPS
• 1M particles - 60+ FPS

Has unstable behavior on bounds collision
