Huh?...I definitely noticed dialogue changes throughout. Like one example. If you have high alpha points when you wake up Lucy with a kiss she says something about her morning breath. Mc says "well I wasn't gonna say anything but..."
But if you had higher beta points he says "Its ok Lucy nothing about you is bad" or something like that and then she calls MC "Sweety" and mc calls her "Angel".. and it shows up in later dialogue too.
That's just one example He thinks to himself from time to time it changes depending on the balance or sometimes you dont get the darker thoughts at all. It's like a hint to where the MC's mental disposition is....so I have to disagree with you, unless I am not understanding what you meant.
Another example, when you are talking to his mother about B.J., mc will say " I will decide what's best for this household" if you have higher alpha points. With higher beta points he instead says " I want to protect everyone" but is hesitant at the idea of killing.
