I only played until I realized that I couldn't enjoy it without the rewrite to fill in the blanks.
If that is all he'll have to do, why hasn't he done it yet, he promised to redo the beginning, yet he keeps making new content to further the story, which means no or very little time to work on the rewrite, so like I said, his priorities are backwards.
New characters, new events to fill in the added days (nobody likes empty or skipped days), new locations, and some more things, that is what it takes to stretch out the timeline without having the writing quality suffer.
I'm also pretty sure the rewrite will remove the flirty/romantic behavior/mood between related characters, as it was first intended to have incest content until BD realized he couldn't because he mainly relies on Patreon instead of SubscribeStar, if most of his money came from SS, he wouldn't have to abandon the incest content, those characters deserve love too.
