Spoiler / walk-through attempt
1/4 : salt + white candle + (flower+hair) + fish blood + soap + eye
2/4 : salt + white candle + (flower+hair) + vial of blood + soap + eye
3/4 : salt + white candle + (flower+hair) + blood container + soap + NO eye
4/4 : salt + white candle + (flower+hair) + blood container + soap + eye
The hair is collectable on the cadaver if you have the scissor. The container has to be filled with the knife.
I don’t know if all is necessary, I definitively had multiple different ending cute-scene with the same ending so >_>
Pretty sur flower or hair is optional.
As far as I know there is no good ending.
