You know, I went into this not expecting much. Most of these 3DCG games are pretty bland, but the writing in this is very smart. The sharp, witty dialogue between the cousin and MC is fantastic and natural. It's a very believable relationship. Rather than having her just naked and ready to go for no fucking reason, you made it a very believable story and slowly developed the relationship to make the incest route one that might actually happen. Not many of these games have this level of writing, and I applaud this extra effort you've given your characters that others often neglect. This is what sets apart your game from all the other clones with similar story bases. I'll tell you right now I don't even remember the other characters of other similar games I've played, but I'm pretty hyped to get more of this content.
As for the game itself, I'm really not a fan of the specific hour-based timing kinda mechanic, but the writing is good enough to make it worth the trouble. The hints are helpful and without them I'd be a lot more frustrated. It's an excellent balance, as anyone who wants to explore the game on their own can do so, but for those of us not interested in micromanaging in the dark, we can look at the mini walkthrough.
I think at this point the cousin is now my favourite, (thanks to the writing) and I'm pretty intrigued to see what MCs boss is up to. The other girls are kinda just there to me. None of them aside from Amy feel like major characters and just aren't terribly interesting. I do like the variety of girls, but feel most seem to be older and not as "hot", or have less than ideal body types. Don't get me wrong, it's some fresh air from the typical and this adds to realism of course, but I'd certainly appreciate some cute young eyecandy as well. As a young mexican girl once said: "Why not both?" Personal preference and all that, but the two receptionist girls, Alex & Daisy, while young, aren't really my cup of tea. I just don't find them attractive. My only other gripe is how the majority of the game revolves around the gym. I'm very aware of the basis of the game, but it'd be great to have other areas more developed and functional to add some extra flavour to your day, or to spend some time with the girls, rather than -wake up, go to gym, go home, wake up, go to gym, go home, with the occasional coffee shop visit-. I'm sure this will be fleshed out in furture updates. Keep up the great work, (especially the writing). This is definitely going to be on my radar.
(PS- The Bill Cosby movie bit gave me some good chuckles. Good shit.)
