So, in other words, he abandoned "Lewd Island" unfinished and created a new "game" recycling the name, theme, characters, and some of the dialogue (and, of course, the annoying minigames,) from the abandoned effort. MC is still a horny dude trapped on a tiny island with his hot but bitchy daughter only, now, things can force them to commit hara-kiri?
Another dev switches horses in mid-stream. Well, I guess rather than playing this new one through until the next time he decides to do this and make us start all over I'll just have to wait 'til - and if - it gets completed before I try it again. Of course, unless there's some sort of "completed game" notification here I'll not likely know if this new game ever gets finished or not. A good reason I don't spend money on unfinished things other than furniture...
(Note to self: Self, if you're still alive in September 2021, this site's still up, and "Mad Cow," CTE, Alzheimer's, or body-jumping time travel within your own lifetime hasn't totally swiss-cheesed your brain you might wanna check on F95zone and see if a game called "Lewd Island [Sanity 2]" ever got completed. Just don't be surprised if you find an incomplete "Lewd Island [inSanity 8]" in its place.)
