I was not expecting to experience a science-based existential crisis delivered via the medium of interactive fiction, but here we are. Genuinely was not prepared for it, but I was both overwhelmed and rather impressed. I genuinely respect the hustle.
Not sure what feedback to give - but having some coloured text to indicate whether a line is a prompt/place name/a thing/words text (should be doable without external modules via using ansi escape codes) probably would have helped to make it a bit more readable. But still, nice work.
