I'm at the doll room right now recording for my YouTube channel and this game is just the right amount of spooky and fun without overdoing the spooks with jump scares or taking away the fun with difficult puzzles. Great Job and hope you keep making more games!
Remember how the horned guy told you "Kaminagas are friends, not enemies"? That's a major hint. Why would a curse god be so friendly to Yasu and not attack her at any moment? Since you refusing has you be cruel to him, you'll want to be nice to him. After that is pretty straightforward.
