The article is bunk, but oddly enough the all time high by Steamdb suggests it’s around tied with DST, Megabonk, Hades II, and a few others at 115k-ish.

Nightreign, as AAA go, 313k at peak, lol.

You can still tell the article is bunk for comparing it to Stray as a cat game. Oh yeah, sure, while we’re at it let’s compare to Hello Kitty Island players, eh? AI logic. Lol
