From what I've heard a lot of people have trouble getting other endings in the game. I'm going to avoid posting any spoilers for a little bit, but observing how your cell phone behaves is critical to seeing the other endings. There's not a huge difference between them visually as I ran out of steam, but I'll update it later with more information. Thanks for playing it! Also sorry for the spooks, I'm not affected by horror anymore so I really don't know how intense people find things in my games.
