A gallery to view all of the scenes would be great. This upcoming training arc would be a great place to introduce the selection of choices (Like in a fight or when answering a test). A menu with all of the romantic interests would also be great but the depends on whether you want the player to have the ability to earn/lose relationship points with the character or not.

A gallery is something I will try to add, or I will take the help of someone to add it. As of now, there is not enough content, where you need a gallery.
There will be no training arc. The training part will be skipped. Nothing Much is supposed to happen during the training part.
I will try to make a menu in the future where you can see your scores.
Finally, thank you for the suggestions.
