Doesn't seem to be working for me at the moment. I'm stuck at a dark gray screen after the 'Made with Unity' fades out. I was able to load the previous single room version but not this one. I use Firefox browser.
This error popped up for me in Firefox:
TypeError: ServiceWorker script at <a href="<a href=" https:="" html-classic.itch.zone="" html="" 17642705="" "="">https://html-classic.itch.zone/html/17642705/</a>ServiceWorker.js" class="redactor-linkify-object">https://html-classic.itch.zone/html/17642705/ServiceWorker.js for scope https://html-classic.itch.zone/html/17642705/ encountered an error during installation.
