Re:1994. 3D horror game

The words were re:1994. A Japanese schoolgirl is trapped in a school building. It said to solve logic puzzles, look for hidden keys and kill monsters. The hero of the game is in a school at night. There are ghosts and evil spirits in the dark corridors. Help the hero find a way to survive. Carefully inspect the classrooms. It is possible to find keys to locked doors. Continue your journey if you use your logic. Don't let the monsters catch the hero off guard.
