Let's start with the obvious: the renders in this game are fantastic. Absolutely top-tier for a porn game. Not just still images, either; Desired Love also features a few animations, and they look excellent as well. The visuals are great, but unfortunately they're the game's only selling point.
Gameplay-wise, it's currently (v0.4) a complete guess-fest. What happens next? you ask yourself. No idea, you answer, let's just click every single room in the game at every single time period. Cool. Lots of fun. Now, I could live with that if the writing was good, but oh man, it is not.
There are obvious and glaring issues with grammar, punctuation, and general sentence structure, but let's put those aside and focus on the story: oops, there isn't one. The game literally opens - serious, maybe five lines in - with the MC's aunt asking his Mom if she's fucking him. Just like that, out of the blue. No build up, no conflict, nothing.
Then, in the first interaction with the Mother, she just straight up grabs the MC's dick through his pants. Zero anticipation. This isn't moving quickly, it's goddamn light speed.
Look, the devs apparently need a little refresher here: incest is a fetish, yes, but that doesn't mean you can just label people related and then any old garbage they do together is immediately hot. Incest is inherently transgressive, and in that transgression comes both the conflict for any given story, and the erotic nature of that story. People acting against societal norms or mores, the danger that puts them in, the relief they find in their secret actions.
This has none of that; not even a shadow of it. As it stands, with whomever the writer is, I simply cannot recommend it at all.
