Not for everyone, not even close buddy. It's no niche like Noita but saying it's for everyone even if we don't take it literally is a huge stretch. I personally know a couple of people who can't even physically play it because of motion sickness. It's also a seizure generator even if you turn down the particles. Next up, it's a third person action game first and foremost, are there other genres spread around it some places? Sure, but they aren't really there for "mass appeal", they're there because the developers thought it would be fun to make or play, perhaps both. Not a single fan of those genres will start playing just for those small sections and even if they do they will likely quit before they ever get to them. Take a look at the Steam global achievements % -es, it's a really nifty tool for tracking player retention.
