About
~ Horror Game: The Vanishing of Tsukikage High Class 2-D ~ "You wake up in a classroom of a high school you don't recognize. Ten years ago, the entire class of 2-D suddenly vanished in a mass disappearance. Explore the abandoned school building while fleeing from students who have turned into monsters, collect the name tags of all 30 students from Class 2-D, and escape." This is the concept of the horror game.
You are playing a horror game set in a school. If you collect all 30 student name tags from Class 2-D scattered throughout the public Tsukikage High School, you will be granted one wish (within the game). After that, the game is cleared. The nurse's office serves as the save point, and you can save by speaking to "Infirmary-chan" who stays there. If you get a Game Over, you wake up in the bed of the nurse's office. "Infirmary-chan" cannot leave the nurse's office. After clearing the game, the classmates do not return to normal (as they have become monsters). *Game progress might be smoother if you record the numbers of the name tags you've found in your profile as you find them.
