I can see both sides.

The studio is upset that people are leaving negative reviews for what the studio thinks are minor issues and will be fixed by release.

But on the other hand, you can't expect people to review a game on anything other than the state it is now.

That said, the gamer community is definitely pretty brutal and known to pile on with negative reviews to 'punish' the smallest changes they don't like, and that is especially true for games that get 'updates', like live-service games, or in this case, games still in early access. Players hope the bad reviews will make the developers change course, but that's no good if they go under before they can.

For Early Access, the type of game they picked (something with levelling and upgrades and 'game meta') is especially prone to rough feedback too, when compared to other genres like horror or platformers or sandbox games where people are a lot more forgiving.

I imagine they needed to do early access to keep the studio going and maybe to generate funds for the next Ori (fingers crossed?) and I hope that doesn't end up being the choice that ends them.
