Definitely Lost-ish. I'd definitely push people to stick to the story if you've played many hours and have just played more of a sandbox mode. Admittedly, I had to look up specifically which cave to get to in order to go to the pit. After spending countless hours running through caves, running out of caves to collect enough resources to actually survive in the caves, and running in circles, I really wanted to complete it.

Definitely worth it. It gets pretty intense and cool once you get further into it and start unraveling the story.

Using the map is super tedious but really helpful
