I think I got 4 different endings, but those were the obvious ones I could get. My biggest issue was that I think I am too tired today to remember the partial phone numbers long enough to write them down - I tried 3 times and then realised it's not my day for that. :D Would be great to have them stick around on the screen longer.
I'm not sure if there is a way to restart without closing the game? That would have made things a bit easier as well.
Now all of that said, it's creepy, it's atmospheric and weird, which is exactly what I was hoping for!
(Slight spoiler ahead, but thank you for rewarding my instinct to jump into the hole over and over again until something happens.
