I'm Super lost.... but this is wat I have found so far...
So spoilers ahead..
Ok, so Walking around I found a Ring next to a Teddy Bear that teleported me to a black room with spining hearts and fallning cubes, you can find the ring by hearing a phone sound
Then I got teleported back to the main area, where the objects seemed to be place in a different order, you have to find the... pimenton (In spanish) and next to it is another ring that sends you to the same heart room.
After that you get back to the main map but there's a line that before seemed faded but now it's persistent, after walking to it a man just appeared and jumpscared me and i f*** jumped off my chair.
Then we retur to the main area but without the shader, then I walk around and near the bear you can hear the ring sound but nothing happens, After walking to the same spot where the man appeared the game crashes.
I managed to do the same but the man did not appear the second time, I wonder if that's all of it.
It was a fun experience but it can get frustrating after a while and probably will replay it again with friends.
