Whaaat, I'm the first one to review this? That's a first for me
Anyway, reviewing v0.10.0 for future reference.
Pros
There's really not too much to criticize here in this first chapter, it sets up the story pretty nicely and there are definitely a lot of interesting beats to the story so far and a lot of intriguing lingering questions. The story somewhat breaks with the usual conventions of Ren'Py games like this by suggesting more of a sci-fi reason for the attraction between related characters rather than having the characters just somehow starting to feel attracted towards one another for no clear reason other than it being the start of the game (like so many of these other incest games).
The renders are also very good overall, I love the skin details in Vanessa's milf character, she's much more believable to be a somewhat older woman than all these 3d animations where older women are pretty much only recognizable by their larger breasts and hips that they all have for some reason.
The sex animations might still need some polishing, they seem somewhat robotic as of yet, maybe that'll get better in the future, but I still count them as pros because they're really not that bad and the smoother character introduction animations, short though they might be, promise something more in the way of better sex animations. So we'll see.
I feel like the gameplay is also pretty well thought out with a mixture of elements that you might see in other games as well but in a pretty enjoyable way.
The free roam parts aren't too frustrating mainly because you're just straight up told when you found all there is to find (thank God for that) and even get bonus rewards for it.
I couldn't discern too many important choices as of yet, other than possibly completely rejecting the mom character as a love interest, so maybe the story will be more straightforward, which I'm pretty fine with.
And the interrogation mode is also pretty fun and original (have only ever seen something like that in one other game) but it might be a bit too easy, at least in this chapter. There's really not much skill required to figure out the right path there and you could even rely mostly on guesswork when factoring in possible rollbacks. But still, it's pretty cool.
Cons
All that good stuff being said... The main reason I can only in good conscience give this game 4 stars is that it's still in many ways a rehash of the hundreds of other games where the "regular dude" just suddenly finds all of his female family members super attractive and wants to have sex with all of them; yeah the reasoning for it might be a bit better but it doesn't really change the basic story.
The characters are also all so painfully clichéd, they might as well be named for the clichés; you've got the kind-hearted mom rediscovering her sexuality amidst a loveless marriage, the innocent, caring sister unaware of her own attractiveness, the more playful "dangerous" sister ready to tease the MC at any given point, a mysteriously but helpfully missing dad figure, and of course the "regular dude" MC with a personality so bland he doesn't even get a face by the animator.
Serah and Mandy are a bit more interesting, to be fair, but also don't stand out that much yet, but that might just be because we haven't really had much time with them yet, so they might turn out to be much more interesting characters than the others.
And while I can live with incest, the necessary clichés of these characters always make me wish for more LI's outside of the family; so far 4/5 of the women we meet are your family members so that's maybe a bit heavy on the incest for my taste.
It's also a bit annoying to see all of the lampshading the dev does on these issues either through the MC or by breaking the fourth wall; lampshading doesn't fix problems, it just highlights them and the fact that the dev is aware of them. Just a weird way to avoid criticism.
Aside from these points, I thought that the introductory tutorial was a bit tedious and heavy on the exposition. That could be cut back a fair bit and only explain the absolutely necessary parts while explaining the rest of the gameplay elements as you get to them; something which the dev does to a degree, but going by that principle could still cut back a lot on the long-winded tutorial right before any sort of gameplay.
Conclusion
So I got a bit ranty in my cons, but overall, this seems like a fine new entry in this somewhat worn-out genre; the story is interesting and intriguing, you have a few different fun gameplay elements that cut back on a lot of the typical sandbox problems, the models are all pretty hot and the renders are good. So what more could you want? Well, fewer cliché characters, but other than that, there's not much standing in the way of this becoming a top-tier game, well done.
