man, you can trigger any encounter by opening the menu and starting it in Cheat Mode. and from there you can look into things you need to see certain scenes and then get them. isn't that quite enough?

you're not talking about ordinary visual novel. it's a game, and you have dynamic status there. it's not so easy to let you choose every scene as scenes require your character to have certain stats or perks, or victories.

a guide to seeing scenes could be cool, automatically updated graph for branching scenes and arts you see. but nothing really stops you to see them yourself.
