Visual Glitchcraft: Snake Through a Broken Display [Snake Rewind Ep 8]
🧙♂️ In Episode 8 of Snake Rewind we go full visual glitchcraft: layering on a suite of postprocessing effects to give the game that worn out CRT look with a modern shader twist.
From retro scanlines and flickering to color channel separation and screen distortion, this episode is all about *style*. We transform our clean pixel grid into something that feels alive, unstable and beautifully broken.
🎮 What we cover:
Adding scanlines with customizable frequency and opacity
Creating a time based flicker effect for a subtle CRT shimmer
Simulating image distortion using sine waves
Splitting RGB channels with a chromatic aberration shader
Combining all effects into a clean shader pass pipeline
This is the moment where Snake Rewind steps fully into arcade mode.

Snake Rewind isn't just a remake. It is Snake with a twist:
🐍 Clone snakes that retrace your path
✨ Retro shaders: bloom, scanlines, chromasep
🎮 Reactive UI, game feel, and juicy feedback
🎧 Music and SFX polish (hopefully we can find free sounds)
