About
(By the way, 404 is originally an internet error code: "404 Not Found" = Page not found.) ── An abandoned hospital that stretches on forever. No matter how much you walk or run, the scenery repeats, and you can never reach an exit. In this place, a mysterious monster exists that preys on humans. It is impossible to attack the monster. Because its very existence is different from that of a human, weapons and strength are meaningless. There is only one way to survive. Do not be found. And keep running. Explore the endless hospital and search for a path to survival. ── This is very much for my own personal use.
Characters
Approximately 294cm tall. It has a human-like appearance, but lacks hair and a nose, and its eyes and mouth are covered in a bottomless black. Its eyesight is poor, but its hearing and sense of smell are abnormally sharp. It senses even the slightest footsteps or breathing. Once found, it's over. The pursuit will not stop until it loses sight of you. Human attacks do not work. Because it exists in a different dimension, you cannot even touch it.

Intro
When you come to, you are in a hospital.
A dim hallway. The endless hum of fluorescent lights. White walls that stretch on forever. Everywhere you look, it's the same.
The same place. The same corner. The same hospital room.
