Here's a short walkthrough for you, with details on the different endings:
Format is "Ending": How to get it
"Alone, Forever": Invite no one.
"I Tried": Invite 1 or 2 people
"I Tried, Peacefully": Variation of the above where JackSkelly is one of the people you invited, or maybe the only person you've invited.
"It's Enough": Invite 3 or 4 people.
"Satisfaction": Invite 5 people. This ending has a special variation, which my sis and I call "the webcam ending", that involves seeing a special scene with Jenny3isMe. To see this scene and unlock the ending variation, choose the following choices during the conversation with Jenny:
"I'll take your word for it."
"No, not exactly."
"No."
"Yes"
"Yes"
Finally, there is an unnamed ending involving JackSkelly. All you need to do to get it is choose "Why?" during his conversation.
I've been meaning to update this game for a while now, I've just been so busy! Also, there's that feeling you get when you released a game of "I've already released this; why should I work on it any longer?" I'll try to give it an update soon(nothing special, just an extended ending, a small gui update, a couple of typo fixes, maybe a little bit of music since the lack of it has been mentioned before, etc.), probably before Dec.25. Maybe I'll include a more in-depth walkthrough as part of the update. "Alone, Forever": Invite no one.
