The original was an emotional journey, a great corruption story, and a hot H-game. This one is a hot H-game. If you treat it that way, you will enjoy it.
The H-scenes are many leagues better than the original's. The art is mostly great and the kinks explored suit the formula better (namely the POV/out-of-view setups). The line-to-line writing style continues to be spectacular. Aya's personality makes her corruption less fun than Laura's, but her dialogue works far better post-corruption so the hotness there generally evens out.
And credit where it's due, the story's intro is good. Ignoring Laura's forced nonsense that starts the route split in the first place, the short arc that establishes Aya as the main girl is very strong. Meaningful and worth reading.
Otherwise, the plot and characterization are just... bleh. Aya had her IQ understandably nerfed and under that lens is still written well enough, but the ridiculous premise of the bet game and the asspull required to start the blackmail gave Luca too much power for the corruption to feel earned. The original held a constant battle of joy and despair, love and guilt - this one feels like an immediate death spiral into sadism and misery porn (hey, maybe you're into that). The admittedly good concepts around Harry's growth are ruined by the power imbalance and obvious inevitability of Aya's doom.
Aya also suffers as an NTR lead in general. Her ditzy quirks feel like weird meta commentary that turn serious moments too silly, especially when the corruption becomes "the voices won" and the schizophrenia becomes a copout to break her mind for free. The fewer endings means lower variety in character exploration, so you're stuck with just a couple brands of fancy character assassination. Having no remotely good ending is of course typical to NTR, but in this case the final nail when trying to care about basically anything; every development is a deus ex machina to make Harry and Aya lose really, really fast. At least this manifests some free use tropes that are pretty hot.
So, read the intro, treat it as the prologue to an imaginary amalgamated Aya Happy End, then pretend the rest is a fanfic of a character you like being reduced to a sex toy to get you off. Hop around the event gallery. Enjoy the hot blonde being put in hot situations. There's enough quality in those for me to call this a great game, even without the corruption and misery porn necessarily landing.
