SPOILERS! Endings guide.

Currently game has 8 endings, with some of them beign quite specific. This listing will clarify everything needed to achieve them all.

Be wary that this guide contains SPOILERS and should not be read if you haven't complete the game at least once or if you intend to beat the game without using any tips.

Also, any of the endings that include calling the police require you to wait for it afterwards (check next 2 visitors and it will come). 

Ending 1: M-m-monster kill!
This is by far the easiest to get. Just let everyone through, don't call the police and big bad will come kill you.

Ending 2: 2 to 1 ratio.
In order to get this ending you have to call the police AFTER you encounter the doppelganger. This means either sending doppelganger away or letting him in and then calling police on any of the other visitors.

Ending 3: Liar.
Call the police BEFORE encountering a doppelganger.

Ending 4: Competent guard.
Let majority (4) of the visitors in and send the doppelganger away. Don't call the police.

Ending 5: True detective.
Call police on the doppelganger with window being CLOSED. This is important because having window opened leads to another ending.

Ending 6: Local hero.
Call police on the doppelganger with window being OPENED.

Ending 7: Not-so-welcoming guard.
If the amount of people you let through is less than 4 and you send doppelganger away without ever calling the police you get this ending.

Ending 8: No fucks given
Game has a mechanic that makes visitors go away if you don't open the window for a 30 seconds and basicly ignore them. Do this to the doppelganger, look away for a second or so and you will get this ending.

That is all of the game endings. Keep in mind that the game is still not very stable so if you can't get certain endings even with conditions met please let us know so we can fix it.
