For the first version of the game, it has more (high quality) content than most games that have multiple updates. THe story is not about drugging your mom/sisters or some crazy magical occult that is all about fucking the PC.
It's a game about the PC (who is already a guy who is a player, the game makes it obvious) with a mother who is sex starved, needing for more pleasure outside her husband who isn't doing anything to help. A younger sister who is secretly attracted to the PC and is slowly (not DMD slow) coming to terms with her attraction to her brother. And an older sister who is close to the PC and with him helping her with some financial concerns, begins to come around with fooling around with the PC. There are also a few other characters that will have a relationship with the PC (the PC's aunt, a teacher who belittled him in front of the entire school, the school's therapist, a classmate who is a friend of the PC, another classmate who is good friends with the PC's younger sister, a classmate who is in charge of the swim team, a neighbor who is abused by her mother, and the game alludes that there will be much more).
Content wise, this game comes right to bat with (HIGH QUALITY) content. The PC can do things with both sisters at night, peep on his parents at night, as well as slightly progress in a 5 part relationship quest with each girl (in this version you can only progress to 2/5 with the mom and two sisters). The other characters I have mentioned earlier only get a slight introduction and slight progress in their story lines. It plays out similar to Teacher's Pets where there is a map with multiple locations and four time slots (morning, afternoon, evening, and night). You can buy items that will help progress certain quests and there are multiple ways of earning money.
Overall, for a version 0.1, this is by far the best beginning of a VN I have seen in my short time as an enthusiast for this kind of game. I would say only comparable to Summertime Saga in terms of content that it had begun with and I'm sure that comes out with each update. I'm very much looking forward to what this game will bring in the future.
