After I Traveled Through Time, I Played Infinite Horror

I traveled to another world and discovered that someone had developed an infinite horror game. The movies used were not found in this world and were all movies from my original world. In order to find out who developed this game, I started playing it. Because I know the plot well, everyone says that I am a genius. I only hope that one day I can know the truth, who else in this world has traveled through time, and why do we come to this world. This novel and its characters are purely fictitious.
