I played ~2 hours on release and thought the game was decent. The combat had some weight, the art style was excellent, the bosses were fun and challenging and the exploration was pretty neat. There were many performance issues which they have since mostly fixed but there were also a few systems taken from different genres that didn't work that well together for me. I didn't play for a while though, so maybe they improved things in that area.

Still, I'm also waiting for the coop, which is scheduled to release with the next major update.

I wouldn't read too much into this news article. Their CEO has since clarified that he might have been a bit hyperbolic and didn't expect the media to pick up on his random Discord post.

I don't quite agree with his assessment of being "review bombed". Most negative reviews come down to the game being released in early access: bad performance, many systems not working well together, being behind roadmap, missing coop on launch and more recently, difficulty. I do get their need for releasing in early access after Microsoft dropped them but it might have hurt them in the long run.
