Don't really get the glowing reviews on this one. If you filter by harem tag and sort by best reviews, it is undeservedly listed as #2 which is retarded.
The story seems pretty unauthentic; not the story in itself but how it's being introduced and how the characters are involved in and interact with it. MC is an unlikable wuss despite having a third leg, which makes the obligatory "wow I didn't know MC had such a huge dick" moments even less of a welcome trope than it already is.
The girls look nice, if a bit uninspired, but carry themselves like no person would. From "he's just a friend/brother" to blowjob scene in half an hour, I know people complain about blueballing in these games all the time but cmon, there is so much buildup and progression between characters untouched that it just looks like some reddit mod made this game, which would also explain the authors obsession with Hitler. When I had to choose if I liked a democracy or a republic more I had to laugh audibly, but what sealed it for me was the realization that the author apparently self-inserted himself into the MC as it's clear he had never been invited to a party as a teen/young adult either. That whole scenario was just bizarre, starting from the invitations up to the bottle spin.
All in all, it feels like I'm being rushed through by an impatient pubescent shut-in from scene to scene while trying to have them connected via the mainstory but it's just so hamfisted and uncreative.
As a "game" or "VN" it's not interesting either. Either choices are irrelevant quiz questionaires or have an "optimal" path, which due to the highly linear nature just means that you always pick the "right" choice via rollback or walkthroughs, as picking the "wrong" choice just means you get less content and/or game overs. Reversely, the affection points for girls are useless, as they only serve as a content cockblock if you make too many wrong choices.
I stopped playing after the house party as it became apparent I wouldn't enjoy, please someone with a working brain tell me it magically gets 100 times better, else I'm gonna skip this one.
