I was definitely aiming for it being unsettling (gotta match the theme somehow). Nice to know it worked!
Thanks for affirming my choice of default theme! And it’s nice to know the capsule* isn’t as obvious as I had assumed (definitely my “I’ve spent 6 hours with this game” blindness).
If you know unity (shader graph & c#) you can look at the assets, but I can do the summary here. I’ve already explained the basics of the audio in a different comment, and the visuals aren’t too complicated. I render normally (without lighting), then have a shader that randomly changes the pixel depending on brightness (50% bright (corners) = 50% chance of changing, 100% (capsule) = 100% chance, etc). I have to save and pass in the last frame to keep track. Then I have another shader that applies the theme’s colors.
*Not important, but I used yttrium because it’s an element I really like. It’s used to make superconductors.
