Well, I decided to give this a look on account of the fact that it seems highly rated and it's been name dropped in some other threads... and I admit that I'm confused. In the sense that, well... this is a decent enough porn dispenser... but the story is barely there and everything is extremely rushed. The content beyond the initial set-up actually makes things worse in some ways. Mainly because it implies that all it took for Millie to fall is a few hours of fucking, and then you can end up with the End of the World ending. I mean, I get that the game tried to imply that the thing that licked her hit her with some kind of powerful aphrodisiac... but unless its effects were extremely long-lasting or even permanent, then it didn't make much sense.
However, the biggest problem is that the game doesn't really establish who any of these people are for the most part. Ken, Millie, Layla, Ren, the unnamed mayor that's Ken's grandfather, Thomas... We don't really get much about them or much of a reason to care about them either.
This is made worse by the fact that Ken is shown to be EXTREMELY stupid and quite pathetic... and so are Millie and Layla. We don't see enough about Ren to know what the heck happened to her that caused her to fall in presumably 1-2 days depending on when exactly she reached the mansion.
There are no continuity errors btw. The key used when returning back in time is the same key the priest gave to the girls and the Mayor when they left. It's just that in that situation, Ken took it back as they went exploring. However, as I said, that makes it worse because it shows the first two girls fall nigh instantly. Indeed, it implies that they were fallen already from the moment of the intro, which makes things rather meh tbh. That's leaving aside the big question of why they didn't just leave in that timeline given that the Mayor slipped out the door...
I dunno. It feels like the dev was trying to rush things to some kind of completion and didn't really think about how it all looked... and then gave up when he realized that the 3rd path would need a whole fuck-ton of content for all 3 girls to show how they ended up in the way they were found in those outfits... not to mention scenes in said outfits... It'd be a LOT of work, and odds are that the dev wanted some ending splits with that one.
Well, that or they died... Fuck knows that sort of thing happens all the time. Unless someone's seen some other circle with a suspiciously similar art-style, we may never know the truth of what happened here.
Still, while this was not a bad way to waste some hours, it was hardly anything I'd except from a game that's rated so highly... This is 3 stars at best in my persona opinion, and for me, not even worth bothering with that annoying rating system in the first place.
