There's only one release remaining - it will be quite large and have all 11 endings. Patreons indicated they wanted all endings at once rather than split. It's been about 14 months to create to this point, and will likely take about another 6 weeks or so to release for patrons (mid April, maybe?) - then it's a matter of waiting for the public release some time later, or a leaker.
Download around the end of March (or your next opening between now and then) and by the time you play all of the routes to get you all the endings, you shouldn't have to wait more than a couple of weeks for the endings to arrive.
Whenever you take the time to play it, it will be well worth your time and, if you're like most of us, you will enjoy it immensely.
