Hi! Thank you for the comment ^^
We thought the objective list in the menu (along with the "objectives updated!" popup), and the ritual instructions would be enough to guide the player. However we might need to make these more clear... Sorry to hear you had trouble with it :(
no offense but it sounds like you weren't paying attention or checking your notes like the game suggests.
kat even explains the rune is in the room with the 3 girls then you have to find something to open the box. its quite clear...
