It's snake but with past selves instead of tail, and it makes it a lot more interesting because of the increase in chaos and strategy. The crt-TV filter really adds to the retro aesthetic, but I wish you'd had kept the text and little clock hand consistent with it. Also, I actually really enjoyed the story in the description- it's really creative and definitely unique. My only concern is the fact that you can scrunch yourself up in the corners of the screen, because it puts the echo out of commission for a while, and it's much more easier to keep track of them if this process is repeated.
