At first look, I was thinking it would be "The Headmaster" that came to the dark side, considering violence, gangs and other themes. Well, it's hard to judge for now, too many things yet to implement. The writing is decent, there are a few typos here and there, even though they didn't bother me much, but I thought it should be mentioned to fix them eventually. Without enough events and activity in the headmaster's office, it's a bit boring compared to linear story what appear from time to time. Will see how it plays out in the future updates, hope it will provide better experience. I also would like to see a choice between bad and good actions more morally complex. More gray choices where is no obvious evil or good sides of conflict.
For now the game mostly lean to building a wide harem of various girls, not that is a bad thing, just I prefer it more when girls are hard to achieve and when not all of them okay with sharing. But, I can let it slide, because, so far, I intrigued about where the things will go. And I like the darker side of this game and that the hero not that simple and has its own baggage of problems to deal with. The fact that the main character is essentially struggling with himself is an interesting concept, that we not see that often, and that's why it is very intriguing. I would even like to add one suggestion from myself, it might sound rough, since is literally came to my mind after playthrough, but maybe you find this concept worthy. At the moment, our hero is a natural badass, and it seems unlikely that he will find serious obstacles in the future. It would be an interesting solution to make his only powerful enemy his alternate ego, which would want to take complete control over his body. It might happen after serious fuck up from the MC side, so alter ego would come to conclusion that, they will die soon if he continues to be in charge. You could make it so that his alter ego starts deceiving him at first, and while we - players, probably could figure it out, the MC shouldn't (at least there shouldn't be always an option to choose) since he is already deep in this mental issues. Next he can start openly blackmail, if MC will decline his suggestion or ignore him for too long, his alter ego could take control over the MC body, for a short period of time, and do some nasty things with girls, or he can refuse to help us in some difficult situation (which won't end nice) that will require his fighting skills or devious mind.
The MC will need either start taking pills (he can steal them), and get rid of any dark influence, but also lose any help from him, until he stops taking them, or earn favors, agreeing with alter ego proposals, and spend them to make decisions that he don't like. As result of this idea, the decisions won't be that simple: choose a route, which you want to go - bad/good. Because you will need to take into consideration what your alter ego want, as well.
At this point I think that's all, let's see what will be in the next updates.
