It's cause of all the complaints they decided to start over
Not true at all.
Complaints were mostly about greedy pay structure and scene structure.
20-50+ for full content. Which is 2-3 few frame scenes every month or 2.
Almost no content for male MC while his sister fucks every last thing thats moving.
None of these were addressed in the rework.
The game was supposedly coming to an and soon, and since their other game did not go off as they expected (They have really weird expectations, and complained about not getting as much as the top developers on the site after a few months of starting their new game) they tried to milk it some more.
The devs are expert complainers, and failers of promises. They give random dates when the next update will be ready. Current update have been promised for like 25 different times. Excuses are "Internet", "China", "The programmer", etc.
All this rework is, is them trying to milk that 600-800$ every month from their whales who doesnt care about money and doesnt cancel their patreon subscription even after like 3 months of no content, while they promised 2 update every month.
