Hello, Mimetoist! Thank you so much for completing our game! We are so glad that you enjoyed the art, the characters, and the experience. ♥
Did you mention Julieta to Odette in Shift 2? You must do this and send the Visitor to her room, and she should be open to speaking with you until Shift 6, during which she will not open her door anymore. If you did both of these things but still could not speak with Julieta, we'll check our code and make the necessary bug fix. Thank you for bringing this to our attention!
