Three, for each kind of medal there is. So, if you have minimum all bronze on levels, you'll get the first ending, minimum silver the second, and if you have all golds you'll get the best ending.
ah, nice, i thought so. also, i was thinking about a bad ending where the servant gives in to the amulet and takes over the matriarch, basically sitting on her big form, indulging himself while the matriarch is under some sort of hypnosis or similar thing. i was thinking about the bad ending being all bronze medal and the ok ending when you have at least one silver medal, and the other endings like normal. though this all is just an idea i had, so dont take this in any serious way if you dont want to :3
