Mathematically, there's two factors:
1. How many monsters you save:
Pacifist, Normal, Weird.
2. Do you get all the shadow crystals and bonus bosses?
Yes, No.

So there could be up to 6 (non-combined) endings I think. The "true" end gotta need the shadow crystals.

Why? Nothing against an Undertale rep. I want Papyrus but they could do something funny like Hero by putting Kris, Susie and Ralsei as one character.
