Game Boy Aesthetic

Inspired by GB Camera, I tried to recreate the game boy effect. It renders the game scene at a low resolution of 160 × 144, the same resolution as the original Game Boy. And it uses a custom shader to restrict output to a 4-colour palette. The palette is defined by a tiny texture (4 px × 1 px), which can be swapped or modified at runtime.

The character asset is from BitGem.
