itch.io

I can confirm what Violetcloud said now, I finally got to purchase the full version, and the option is available there (although I didn't check the Demo to know if that's where you're coming from)

There's a F2P in-browser version available that I'm not sure it's official (nor that it's up-date), but there's a "Trypophobia" setting available in the Accessibility settings there. Judging by all the credits and everything else being the same as from what I've seen from livestreams and gameplay videos, I think it's official and up-to-date, just not linked here.
