making visual novel

I've got renpy set up and I'm working on making an little viusal novel game, thinking the story follows player as they go camping with their family, everything is normal, as normal as it can get for this family

then a few strange things happen, weird noises at night and items missing from their campgrounds, this concerns mc and they bring the concern to their family but they brush it off, then in crack of the night they wake up to their family GONE.

maybe the game has two pathways of ignoring it to enjoy the camping trip before it eventfully goes wrong or exploring it

I'm also maybe considering how to put my monster characters into it :} in an way where they are like driven by the story, not the focus of the story, but i hope i can slip in hints to their relationships
