The gameplay loop is really fun. The procedural generation of caves and encounters make things fresh. Sometimes you get sprawling caves of tunnels with claustrophobic feeling, sometimes set of "bubbles" stacked on one another, sometimes you get caves so big, you cannot see other side of it. The community is usually pretty welcoming even for newbies. The amount of content is huge, there is tons things to unlock (if you're into this kind of thing).
For me one of the best (if not the best) coop experience. Way better than Helldivers.
