How do you upgrade your stats?
Just play and they will get upgraded, no need to focus on them really.
It's just that you need one strength for Andre's route. Is there a certain threshold? Or does it just upgrade as weeks go on?
Oh, that. You will get upgrade during Mercy's storyline, and another one somewhere else, we really can't remember.I'll ask our dev to just remove those requirements, since we never really did anything interesting with stats.
