I'm just gonna say this but this game really does need a new game plus or a free roam when you have beaten the game 'cause there is a lot of missible content or potentially missible and I don't want to constantly have t.... just to get new scenes that I missed
I would recommend implementing either.
1 Chapter select with the scenes the game tells you that you missed so that way you can easily grab them
2nd A new game plus feature would allow people to come back with the social stats everyone has to make maxing them out easier to get the scenes
3rd This would also make playing the higher difficulties a lot more manageable and could add more replayability
