The expansion of the black hole has disrupted the magnetic fields of the Milky Way and the galaxies within the black hole, generating a time-space travel function. Gait Helbas, a young adult, was teleported to another planet while sleeping. There he met Catherine Boot, who was also an Earthling, also teleported there, and also a young adult. However, she was captured by strange shape-shifting creatures. Gait decided to rescue her, but the path was filled with bizarre and violent creatures. The character has no tedious level-up mechanics. The goal of the game is to defeat the Boss hidden in the wall. Then search the Boss arena for an exit room to complete the current chapter. The rescue of the female protagonist will be revealed in subsequent chapters. The game features no complicated mechanics. All you need to do is eliminate the monsters chasing you, escape the territory of powerful beasts, and slay the demonic Boss in the wall—using your movement skills, precision shooting, and wits. The game recreates a dark, unfamiliar, and isolated survival environment. You can locate enemies by sound and shoot at the monsters lurking in the dark. You can discover the traits of monsters to escape their kill zones, explore the layout of the labyrinth to find the final Boss, and perhaps even experience a wonderful dream. Uncover the final Boss’s weaknesses and take it down.
