The free roam will be deactivated in the next version because I want to implement a few changes.
About choices and story branching: sadly, this game is pretty demanding in terms of time and assets required to create every scene, I'd love to implement different routes, outcomes, and variants, but that automatically increases the development time exponentially. I'm not saying that I gave up on implementing choices or multiple endings, I'll implement those features when the game is near to finish (Because it's way easier)
