Given that their patreon goals have met this tier:
Large Shrine Expansion!
Two full doujins (16+ pages) a year! Aside from working on the bi monthly projects, I will also work on full doujins intended for publication and sale! This will of course be free to the appropriate tiers once they are completed! Equellum/Fabula now will be updated weekly!
And it's been, well... 20+ days since the last update (3.5, which doesn't have the artwork people want it for [also, the reason why it's unavailable is most likely because the uploader gets it from the same place I check and whoever provides hasn't done so since the original googledrive link for it was scrubbed and the dev switched to a different hosting service]) I think it's safe for me to reiterate that they've probably bit off more than they can chew as a single person working part-time. Double part-time actually since their main thing is commissioned artwork for those heavy-hitter patrons.
TL;DR: Might wanna curb your expectations on how soon content will be added or even when this game will be completed, I know everyone's impatient but the wait will be more bearable if you're prepared for it.
