1st: Characters aren't indoor/vents bug: If characters attack you when they aren't indoor/vents, that's not a bug. They did already showed up on it and when you were about to look on it, they were already gone inside your office, and then: Game Over.

2nd: I can't save progress bug: Ok, I'll tell ya something about it: So, when you'll about to close the game after a lot of progress done, go on rar or zip of the game and click "Yes" that maybe should show up in it. That should save your progress at all times.

Reminder: It will not work if you close the Rar/Zip File. So keep it open while you're playing and going to close the game.

3rd: Characters keep jumpscaring me in all 20 mode bug: Not a bug, man. You'll just need to pay more attention.

and this game was also supposed to be hard, because a easy game isn't funny at all.

Anyways, good luck on it.

4th: Characters camping in doors: If some characters try to camp on your door, that's not a bug. It's just their AI in the supposed night.

5th: HOW THE CHARACTERS ATTACKED ME IF THE DOORS WERE CLOSED!?: It's because you couldn't fully close the door on them. That means the characters got into your office before you could close it.
