I can't seem to keep her alive for more than a few minutes. The little face at the bottom will light up, but her stats are normal and she doesn't want to talk. Then, the little droplet symbol will light up, which I assumed meant she needed medicine, but apparently that wasn't right. The "???" button also lit up, but clicking it didn't do anything. And then she always ends up dying.
I actually like how the UI is unintuitive (having to memorize which of the three main buttons does what), and having to hide her whenever someone knocks on the door. I think this would kinda be fun, if I could figure out what I'm doing wrong lmao.
