Since the gameplay is so much about 4D, clarity in what you see becomes more important and the extremely low resolution actually impairs the player rather than serve a positive (typically 'leaves more to the imagination').
It wouldn't take much of an effort to double or triple the resolution which I think would help the gameplay.
So it is as low res as it is because it is a bunch of voxels simulating a 4d camera.
The dev put out an interesting video on the topic.
The sensor to see a 3d scene is 2d(eye or camera). What is being done here is simulating a 3d sensor(for a 4d world) then we are looking at this 3d sensor using our 2d sensors (eyes). I don't know if this is the common way of rendering these 4d physics simulations. But it is the first I have heard it described this way. It is also why the narrative of the game focuses on eyes, because that is what it is doing.
If this is 4d doom, i wonder what 4d quake could be

The person goes over quite a few technical details on their Youtube, though they talk about a bunch of other coding experiments too.

I guess taken to the logical extreme, what does the brain of someone/thing that's good at playing this (or any game of N dimensions) look like?
My curiosity is if this is like you suggest, ingrained patterns, or if there is actual slow down with age. I hear different opinions and am finding it difficult to navigate as I deal with my own, albeit mild, aging.
I actually noticed serious mental decline when I was burned out in my late 20s. There were real physical symptoms like not being able to look at a text editor for more than 2 minutes. Post recovery of that, I actually feel like my brain recovered a lot once I started learning languages very seriously (mandarin and japanese), starting a few years ago. Brain feels healthy now but I'm acutely aware of where it's not as sharp as before. Playing around with this felt a little like when my brain is trying to build a new grammar dictionary.
The only answer would seem to be an extra axis of rotation, but (a) doesnt work well with existing input methods, and (b) would be even more of a brain-breaker
But in 4D there isn’t really an equivalent control, so it ends up feeling more like toggling something you don’t fully understand.
Ordinarily, a 3D scene rendered in 2D only allows you to see a cone from your eye up to the first surface the ray encounters, thus defining the 2D projection which you see.
But you can make the surfaces transparent so the ray continues, and each additional surface adds a bit to the final pixel. This can look like a mess if you stand still but if you wiggle your movement left and right (or any other direction), your brain suddenly manages to process it into the full 3D structure.
Can something like this be done in 4D?
