First, for those who are familiar with me... Yes, I did play this. Why? Something about the way it was presented in the Getchu page said that there was more hidden beneath the surface than a standard oppai-nukige. Thankfully, my instinct was correct, in this case.
Now, for those who are curious, this game is a straight-out harem, from beginning to end. This game's primary attractions are the comedic reactions of the heroines and the way they and the protagonist slowly 'fall'. It is like watching a train wreck in slow motion... it is too fascinating to look away from, yet you know it is going to end badly, lol.
The protagonist, Yuki, is a somewhat hetare-ish guy who does his best to disappear in the classroom and has trouble speaking to others. One day, out of loneliness, he opens up the Tomefure app, where young guys offer young girls a place to stay for free without strings attached and signs up. The girl who appears at his door is the class idol, Sakurako, who immediately crushes his hopes (sexual fantasies) and basically does her best to leech off of him, dragging a bunch of other girls into the mix.
This story is all about a bunch of young people too afraid to create real relationships or who have huge problems in their normal lives essentially huddling together and gradually becoming contaminated with this weird 'small community' Stockholm Syndrome thing. I spent most of the game laughing or in a state of 'frustration' (yes, that kind of frustration), because the process of Yuki and the girls' morals collapsing takes a long time (despite being a kinetic novel, this game took me almost 20 hours to complete) and actual H and near-romance (there is no true romance in this game) doesn't get going until you are about 7/8 of the way through the game.
In terms of writing, the basic quality of the main writer is pretty low. I'd say he is somewhere below the baseline for charage writers, which is generally bad in any case. That said, because of the way the 'story' is presented, his lack of writing skills doesn't create as much of a negative effect as it might otherwise, even in a charage.
If you want a comedy ecchi harem VN to read, this is probably the best option you can find for the last three years. The whole thing is so absurd that I couldn't help but laugh out loud (a real lol) on dozens of occasions. Don't expect 'healthy' romance, since the whole story is based on the characters' gradually losing their common sense morality about relationships as they sleep in the same room (there is more to it, but I won't spoil you). However, if you don't mind that kind of thing (or if you love it) this game is a fun read.
PS: Yes, I surprised myself with how much I got into this one.
