I think a bunch of sites have been blocked. Even with a VPN I can't open my own links on itch (although I can on other sites). You can download the current version free from my patreon: https://www.patreon.com/RanliLabz
Glad to hear it! The Zombie scene (and one of the locations) is only available if you played the Cis blowjob scene; the nun is the only new named character (tho quite a few background characters appear in this one!); and the main new location is the Cabin Foyer at the end (although you see a few location previews in the nun scene).
At the end of all the scenes it goes to the 'to be continued scene' :) - choosing none of them as PLIs ends the update.
