I like the heroine and the overall concept. Too bad all the good stuff is located into the blackmail/asshole route. If you slap him you get nothing.
The curse of the female protagonist game keep going on.
I agree. Most authors (and most players too, to be honest) just have a very faint grasp at what a satisfying BDSM relationship could be, and how such a relationship develops over time, be it a D/s or a S/M one. Beyond the bullying scene in class minutes only after the protagonist introduced herself, I also had a good chuckle at the (conclusion of the) scene at the spa.
This being said, the game shows promise. I don't count myself among the crowd that is bothered by the CG placeholders, since I know that creating good art always takes time, especially gorgeous 2D art. The character sprites are well done, so I have my hopes up for the rest.
I had played an older version before testing the new one, so I was pleasantly surprised by the addition of several interesting characters to the story, and am now curious to see how their interactions will unfold in the future. Maybe are there more characters planned, like teachers or parents ?
As the author said, the game needs time (and some serious polishing I guess). That doesn't sound unreasonable if we eventually get to play an enjoyable VN.
