There’s one hidden detail on what you should do to get a good ending, but given the time constraint we didn’t add any hints.
Spoiler
You're not supposed to fight back the ghost, just end your turn every time. We were planning on adding an extra section to send a message about de-escalating conflicts and that'd mean you don't have to fight back the monster, instead you should try to understand it first. But oh well. We didn't manage to *actually* put this into the game.
