My first 5/5 here in all categories. I'm super impressed. There's something really special about making a game where your only first instructions are "Click M1", and for the rest to be mostly intuitive. I did start to lose a little interest in later stages where I was really struggling to find the match, so perhaps something like a "cold" or "hot" hint mechanism would be nice for impatient players like myself.
So, the music is perfect. I see you use Firewheel/Seedling, and I'm assuming you're doing some live synthesis or at the very least playing samples - which again, not only super impressive, but it sounds really good. I'm happy to see someone making use of the more advanced audio systems now available with bevy & adding to the atmosphere of such a great concept.
The shaders fit a feverdream perfectly; the imposed image is like what you see if you close your eyes in a bright room, like an afterimage. Just enjoyed everything here from presentation to sound to visuals to execution. Incredible work.
One thing I found really interesting (and I'm sure many others ran into this too) but it's surprisingly easy to just.. discard your periphery at first. I was having some difficulty positioning until I looked at the sides of the screen and was like "Oh, those are completely wrong, I need to worry about my perspective". Almost like how people almost never look up in FPS games. Really got me thinking in a way I don't usually think with this control scheme.
