It's working now!
I managed to get two endings, the crucifixion ending and the mother's ending (or something like that).
I saw that there's RNG in the rooms, so maybe that's why I couldn't quite understand what was happening. I don't know if the endings I got are related to the protagonist's story (it seems like the mother's ending is), but I'd like to know more about her.
I liked the game's art; the character painting in the dialogues and the protagonist in the mirror are very good.
I saw that this is your first game, so please keep creating more and more games!
