I've already posted a comment like this, and I want to post it again, hoping that the developer will add the ability to fully heal Tavi and restore her to her normal state.
"It's been a long time since I've felt such emotions from anything, including sadness for Tavi, and I'm still sad even though several days have passed.
I really hope that future versions will include the option to fully restore her to her original personality. Right now, it feels like everything is designed to break her, not restore her. It seems like there is an option to restore her character, but it's terribly limited and feels unfinished. Unlike the version where she breaks down."
