Noone likes situations that go wrong, but the fact is that they are happening anyway and that they are usually unpredictable. The main hero of the game happened to get into the circumstances which can drive him mad easily.
The gameplay is really simple. You should move with the standard buttons and use others like F to turn on the flashlight etc. The playthrough is about 15 minutes in total, so it will not take much of your time, though you will be amazed by this simple and astonishing story.
