This is my take on the "hole" genre (All in Hole, Donut County): a hole that moves, swallows everything, and grows. Built from scratch in Unity:
physics-driven hole with real rim collisions (the Donut County two-universe trick, the ground is never actually cut), hand-written HLSL shaders, event-driven VFX, and editor tooling that generated 300+ collectible prefabs from an asset pack (also it automatically made "photos" with transparency for the logos of each of them).
