This was cool! It was chilling to see the patterns become more and more... lifelike, I guess, as you dig deeper (not sure if that's intended or just coincidence/confirmation bias on my part), and the music gave me this odd sense of dread - like I was venturing somewhere deep and unknown.
I didn't quite reach the bottom (bombing through dense zones got to be fairly repetitive after a while), but I enjoyed it nonetheless and feel inspired to check this stuff out a bit more myself!
