Merry Christmas, Three.js community!
Here’s my moody first-person bird shooter: 
RAVENFALL. Ravens perch on power lines, circle overhead, and dive-bomb your face. Shoot them down.
Notable features:
-
Mobile controls using nipplejs (dual joysticks, sprint via force threshold)
-
Verlet wire physics: birds perch on cables and actually weigh them down
-
State-driven bird AI: perch, flock, swoop, attack, retreat
-
GPU-instanced bullet trails with custom billboard shader
-
Instanced feather/blood particles on kills
-
Multi-kill piercing (strict ray-line check, not bounding spheres)
-
Scoring combos: streaks, swoop bonuses, sniper distance, multi-kill rewards
-
Dynamic shadow frustum following the player
-
GLTF gun with shooting animation
-
Wing-folding via animation frame freezing (no extra assets)
-
Config-driven design: tweak bird count, swoop chance, wire stiffness, etc.
Hope it helps someone get started or just have some fun blasting ravens!
