Don't wanna spoil the whole game, since it's free and pretty short, but wanted to share this last chase as it's pretty nutty and can be somewhat confusing.
1) The phone will glitch and the ambient noise will get almost unbearable when the monster is near.
2) The phone will show brief images of photos of people the protagonist knows when you're in the same room as a photo she needs to collect to unlock the proper door.
3) It is possible to accidentally go to the place where the door you need to unlock is (before you unlock it). This is a dead end.
4) When the door unlocks it will show it opening on screen, and the various room doors won't open so just book it down the hallway it forces you down to get to safety.
5) Yes, the monster teleports in front of you in certain rooms. You'll have to bait it out to reach certain points.
6) Yes, I got lost. Entering a door in this sequence gives you a bit of breathing room from the monster so sometimes I felt I had to exit a room prematurely to evade it, which did not help my getting lost.
