TLDR: Scroll to Synopsis.
Story: 9/10 - The overall introduction is unique, which is a major plus to me. No attempt to use the worn out "moving to mom's after <insert tragedy for father here>". In v.23, the 'shock twist' was also a very good and unique touch as well, along with the 'comeback'. The sexual aspects meld in with the storyline, thus far, though some of the sexual aspects might leave a few thinking 'Yeah, right!", but not so outrageous that it would be outside the realm of possibility.
The story so far is a fresh concept that is being nicely executed.
Renders: 9/10 - Excellently done. With the female characters seen so far, a very good variety of body types, races and ages.
Characters: 10/10 - An excellent mix of personalities, rather than the same tired 'cookie cutter slut' types. Ranges from innocent, to a grandmother (not elderly), and a bodybuilder.
User Interface: 9/10 - The interface is not intrusive on the overall display of the renders. Only a couple of occasions where using the H key to hide the interface was needed to see full detail of the model that was being displayed at that moment in time, and only to hide the speech box. Even with the speech box visible at those times, could still see what was displayed fairly well.
Animations: 10/10 - Excellent render and animation work. The animations have a pretty high FPS rate, giving them a smoother, more realistic movement. Couple this with the option of multiple viewpoints for most scenes, increases the overall score in this area substantially. I would give it an 11, but 10 is high enough.
Male Protagonist: 9/10 - The male model is an actual ADULT, with a much more realistic body frame and type, along with far more realistic genital size. No anacondas or sewer pipes between his legs.
Synopsis: 9.5/10 - This is one title that I may contribute to, financially. The Developer has presented a fresh approach and story with enough activity with each of the characters to increase the playing time of the game, even at this early stage. With the 'character hint' screen, the need of a walkthrough to see the available content isn't needed. There are also a couple of directions that one can take with at least one of the characters, as well, giving a bit more in the way of choice and options. I can see the possibility of relationships being possible in future development, based upon the story so far. Definitely one to check out and follow!
