"He wasn't beaten, he wasn't really emotionally abused, he wasn't harassed or bullied by people around him"
I have to remind you that you are currently reviewing an Ongoing game, it is far from being completed.
Therefore, such assumptions like the one I've quoted from you are factually wrong. You haven't met his dad yet, nor seen any portion of MC's past yet except for Anna and Alice.
In my humble opinion, I think you're writing way too much on the only aspect of the game which cannot be objectively criticized due to the game being currently in devlopment.
I suggest you don't dwell on this aspect too much as long as you don't have all the elements.
