Wether I chose boy or girl it said "instructions unclear" "loading trigger warning" then gave a black screen with a yellow box left it for a few minutes to see if it was loading something but it didn't change 

Hello! The choice is a reference to Pokémon games, where i.e. Prof. Oak at some point asks if you're a boy or girl. Either option gives the same result.

About the game not starting after the loading yellow bar, I'm not sure. It's supposed to keep on with the text, showing the "all characters are 18 or above blablabla" stuff 🤔

I'll check that out and fix it if it's an error ✌🏻
