This game is a true gem. Its easily one of the best Ren'Py games I have played before and I would wholeheartedly suggest supporting the creators.
The writing, the models, the renders - literally everything about this game is of high quality. The main character is actually intimate and has writing that doesn't seem awfully cheesy or forced. In fact, the main character is rather unique in the fact that he isn't just some pervy teen/20-something year old but an actual accomplished college athlete.
On the side of models, you won't see many of the familiar faces you'll normally find in these types of games. It looks like most of the girls are fairly unique to each other - ranging from clothes to skin tones to expressions. The black characters actually look like people instead of strange, dark-skinned white characters and actually have naturally textured hair (or at least higher quality ones than you'd normally see). Additionally, the body proportions for everyone range from full on bimbo to slender and petite. The clothing options are mostly realistic as opposed to the fresh off the set of a Brazzers shoot attire that other games have.
The game also gets points for having the main character actually wear clothes that aren't the default "Big Brother" styled ones. Other male characters actually look human as well which goes a long way.
The renders are incredibly well done. Good lighting, fleshed out backgrounds (although some appear to be a little bare), and no odd filters. This game has some animations in it and they look incredibly smooth in action. Even the still shots are great with hardly any noticeable errors.
In terms of gameplay, this one is definitely not a grind fest. Its a visual novel and it looks as if you will have the potential of romancing everyone. While that may not be everyone's cup of tea, its a great thing for the game to include as many of the ladies are quite lovely.
In short, I'd say download this game and support the devs. All the praise it has received from other reviewers is completely warranted.
So, that review is not really that accurate anymore. As the game progresses in its development, the author is really just making this a generic harem game with a self insert.
The story has progressed a bit with some hamfisted stuff about corruption and conspiracies about the school, as well as poorly explained reasons why all these girls you're just now meeting are moving in with you. Additionally, there are no real consequences for your actions. Your girlfriend and her friend are virtually fine with everything you do, as are the other girls you fuck. The actual incest plotline is kinda still there but its so muddled now.
The models and renders are still fine for the most part. The base models are getting reused more and more to the point where nearly every girl is starting to look the exact same. And there is now the ongoing trope of going to bed with the amount of girls in the bed with you increasing.
At this point, I'd either say avoid getting each update as they come out and instead grab them every other month if you still want to attempt to follow this "story"
