I don't know what it is that makes me like it so much, but one of my favorite things to see and read is when in a story where the MC is blackmailed into something, that it is just the catalyst that starts the events and the player, me, is given the chance to make choices of acceptance and the MC not only accepts the situation, but also finds out they enjoy it and are even willing to take it further on their own.
I see many times where players complain about not being forced. Where if they fight against the control then it leads to a bad ending/game over. I disagree with that mentality, and maybe it's just me personally, but if the story is "do Y and we will/won't do X" and then the player refuses to do Y how do you not expect an abrupt ending?
Anyhoosie, more to the point on this game. I'm iffy on the water color visuals, I like it, but yet don't. It stands out against current content, but reminds me of a more simple time with these VN/Games. Either way I'm not docking a star for it. The story is believable enough, there is suspension of disbelief. It's not too crazy too fast. The MC can either buck against those with power over her, reluctantly give in, or accept and enjoy.
I don't like the blackmailer, for all the right reasons. I don't like the general male student body, for all the right reasons. They aren't really meant to be likeable in this situation given that they are immature high school boys dealing with a exhibitionist/naked girl. They are written realisticly and not as mature adults. The adults are written to be mature for the most part. Both Doc and the gym coach are written to be of a "fuck it, if you're ok with it then I'm ok with it" mentality when handling the co-ed'ness of the situations as presented.
This game is early on, I want to see more, I want to see Emily (MC) become more and more slutty, become the school slut, enjoying it. Ultimately I want to see a happy ending for her, what ever that may look like. I would have no issues with her ending up as a stripper happy with her job, or a legal prostitute making serious bank and enjoying life, or even just continuing and going on to university, slutting it up there while she actually studies and ends up making something of herself. So much potential and possibilities with this story. As it stands I like it a lot and will watch for more.
