In v0.11, I made the game more frightening.
Specifically, the addition of enemy voices when dead and approaching, and changes to the player's sight distance.
Until previous version, the player could see up to 10 meters away, but now it's 6 meters.
This will let enemies to emerge from the darkness and should feel more frightening.

- Nurse-call calls two enemies (only one in previous)
- Monitoring camera calls two enemies (In previous, it generates big sound and enemies around hear and come)
- Change the gun's landing position to make it more convincing.
- Change sight distance from 10m to 6m.
- Decrease enemy's speed when he's guarding his face by arms.
- Decrease the number of monitoring cameras.
- Enemies escape after attacked to the player.
- Increase variability of enemy's face.
- Add a model of stretcher in morgue room.
- Fix a linen room. Enemies couldn't move sometimes, because a linen room had a closed space.
