I just picked this game up and am finding it quite enjoyable. About 20 minutes in, still going through tutorials and what seems to be fixed dialogue on a storyline.

My question is to those who have been playing this longer.. Does the game repeat itself when starting new games? I was hoping that this game would be similar to FTL, where you get to experience a random world each time. I'm afraid that this game is going to end up being repetitive.

Is there a free roam, or sandbox mode, in this game, that doesn't necessarily require to go through dialogues? Like a simple rogue-like?

It's linear. But there's a lot to play.
