Uhm, yeah, the unscreenshottable videogame (demo), I call it Noise Vision. You'll have to look at videos attached below, lmao

I love rendering tricks like these, they are usually so unique and weird to game design around. (That's why there's no gameplay in these)

Was inspired to implement this myself after watching a couple funny videos on YT. Except this one is rendered via an actual graphics card and also has s̸t̴y̷l̸i̴z̵e̷d n̷oi̸s̶e̵.

The effect is achieved by rendering everything (mostly geometry edges) to a separate buffer than XORing that buffer with the main buffer seeded with noise.
Unfortunately, Godot really doesn't like tricks like this fOr SoMe rEAsOn and I have to refresh the main buffer from time to time.

Again, horror/walkingsim game material, I have an idea how to make a cool enemy/monster for this rendering trick too.
