This game is disappointing because I really would like to enjoy it. The renders are all good and there's an abundance of animations, all of good quality. Visually, the game is very impressive, especially since most scenes have multiple angles that the developer made sure were consistent with each other.
The release schedule is good, the amount of content is respectable, and the writing, while bland, is above average and generally mistake-free. By all means this should be a 4-5 star game.
The problem is things start to fall apart outside of the visuals. The plot is frankly ridiculous. Even accepting the very loose premise that there's some super rich secret sovereignty that recruits its heirs from completely unknowing candidates (why? wouldn't having some knowledge about this allow them to be better prepared, or vetted?), why would some random 20-year-old undergrad MC be qualified to do cutting edge engineering research? In the same vein, why would MC's dad be able to start some car tinkering business out of his garage and outcompete F1 constructors who spend hundreds of millions in R&D?
Even if you manage to turn a blind eye to the ridiculousness of the premise, the gameplay loop is just... not good. The plot is too consistently there to be ignored altogether, but ultimately the game doesn't really give a damn. It's floating in the background in the most annoying, vestigial way. Every day you essentially have to skip though panels of inane technobabble ostensibly related to the science-fiction premise of "infinite energy," while the real focus of the game is all the wet holes the game throws your way.
I'm aware that the game is called Milfylicious, and the preference skews towards women of a certain body type. But if you told me every model used one of two body models, I would probably believe you. There's such a shortage of body type diversity that it's hard to differentiate them. This is made worse by the fact that the game just introduces you to love interest after love interest without any regard for making you care about them.
You're just given women with no real personality, who are all obsessed with you for... reasons... and all with similar body types. You'd be forgiven for not remembering any of their names. It quickly devolves into repetitive sex scene after repetitive sex scene, interspersed with bits of technobabble that even the game fails to take seriously (so why should any of the readers?). If you're looking for any kind of seduction, or eroticism, or even the barest bit of tension or build up, you'll find this game completely lacking.
Worse still, a lot of these sex scenes are voiced, which in this case is often a detriment. Most of the sound used are not properly balanced, so you'll here lots of humming background static, audio that hasn't been properly pop filtered, or simply soundbites that are suddenly too loud. They add very little, since most of them are just random clips taken from porn, and many times don't fit what's happening on panel or suit the characters as they're written.
There's also an amateurish quality in the writing itself. The best way to describe it is that it feels like a teenager's idea of an adult fantasy (see the aforementioned underqualified garage operations outperforming billion dollar industries). References and depictions of food, locations, organizations, etc that feel very topical, like the author just googled "what's the best [X]" and added it in to try to sound educated on the subject. The women are also written quite heavy-handedly, without much nuance or care for their characters, which makes you wonder if the developer's only contextualization with women is through porn. You also have odd gaff, like apparently not knowing that Puerto Rico is part of the US, which threatens to take you out of the moment.
Now none of this means the game is bad, per se. If you enjoy plowing through a bunch of beautiful-but-empty buxom women, and indulging in a harem power fantasy where you're the literal lord of the castle, this can be the game for you. But if you want a story and characters to match the quality of the renders, you're in for a huge disappointment.
