I wanna give it 5 stars, because it is nearly there, and I love the "school setting" games, but there are some minor issues holding it back. Those being:
-Not many, but some, spelling errors. (Easily fixable.)
-Grammar is definitely off at times. (Engrish, if you will.)
-Some choices that you make will lead to results that they most likely aren't meant to lead to. (Ex: When Leah tells you about her potentially moving to the city you're going to college in, you can tell her that you don't give a shit and she'll still grind on that ween. I doubt that's the reply you would get for telling her you don't give a shit.)
-Although the freeroam parts aren't a major focus in the game, and there aren't many of them as of now, they can be a little confusing to navigate. (Ex: When you're at the party at a pretty large house, you would expect there to be more areas in the free roam, and the arrows just randomly popping up to go from place to place leave you feeling like you might be missing an area. For all I know, I actually might have.)
-Animations could use a little work. They aren't THAT bad, and will probably get better as the game progresses, due to the dev gaining more experience, but they're not great either. (I'm just grateful that the game at least has an attempt at animated H-Scenes, instead of just still images, or the sorry excuse of multiple still images that go back and forth.)
-Hate to have to be the guy to say it, but I'm still gonna. It's another MC with a monster dong. For me personally, if it's not gonna be a "fap-fest" type of game, and you're going the story route... Don't give the MC a third leg. It isn't realistic, or captivating in any way, and just feels like a cop out because it's a porn game.
Those minor issues aside, this game is solid so far. It's still too early (0.15) to tell any further, but the foundation is there for a good game. The character models are great. The story is enough, for lack of a better word. It isn't amazing, but it isn't awful either.
All that being said, good luck to the dev with the rest of the game. There's some 5 star potential with this one, and I'll be looking forward to future updates.
