This is so good!! Just one little thing to point out:
[SPOILER WARNING]
MC finds his parent's room and runs into the king who has killed them. I chose the option where he finds a sword and stands up to the king stating that he has killed his family. Once Lancelot steps in and saves him, MC asks him if his parent's death is like an illness and if they will stop being dead at some point.
[END SPOILER WARNING]
I find this naivety weird because MC just pointed out that they lost people to killing implying they understand the concept of death. I recommend changing this if they are intended to be naive (which is understandable since they are a young child at this point in time).
