Haha.
Depending on the choices you make in the dialogues, then you have different ones, there are extra dialogues if you don't promise anything to Belinda and then you look in the pool, for example.
It also has 3 types of endings, the ending of not reaching the end (if you don't go to see the guy outside until the end, when you go it's game over for breaking your promise to go out and inform him), another ending if you don't talk to him uncle before going to the third floor (which is the bad one), and the good ending of going to the third floor after talking to your uncle and him explaining how to open the door, that one has special music composed by neffex.
Too sad you took the audio off, the music of the minigame gives goosebumps with the voices singing in a gloomy way "they belong me", or the theme of the end of the game "closer to heaven", that's nice and a little sad .
