Does anyone know how to skip this mirror part and how to increase my relationship with Violet? Mine is at 8.9 and I don't know how to increase it; it just asks me to use her, but nothing changes.?
Regarding the mirror: you need to keep grimacing in front of it.
For relationships, there are:
1. Fortune Teller.
2. Special items in stores.
Relationship numbers are not needed for gameplay – after around version 0.68, everything is handled using the built-in help system.
