My honest rating would actually be a 3.5, but since F95 doesn't allow that, I can either round up or down. I decided to round up because the positives generally outweigh the negatives.
On the positive side, this hits my mind control fetish and choices are frequent and matter a great deal as to the way the story goes. My favorite aspect of visual novels is making choices to affect a story and I always try to make it clear to devs that I don't need sandboxes and minigames. This gives me what I want from a visual novel. There are a lot of different routes you can go down. Some end abruptly, but some are really well fleshed out.
On the negative end, the art is unappealing at best and ugly at worst. I have yet to experience a game that perfectly combines my mind control fetish, good art, and a good story. Usually one of the three is always missing. In this case, it's the art. Several of the girls are just straight up ugly.
On the whole, a pretty good story, even if not perfect. Worth it if you're a fan of games with mind control like me, or if you're not like me and you enjoy the more eccentric art styles that sometimes pop up in VNs. If you don't go for either of those things though, I can't imagine it'd be worth it to play.
