Had me in the first half, but then Part 2 just drops the ball.
Going to break this into 2 parts because of just how different the part 1 and part 2 directions go, so let's start with the good.
Part 1's focus on many in-game events involving combat, Kirito being distracted in the heat of battle, Inoda's invisibility skill, and the fact Inoda seemed to be a devious mastermind of trickery and subterfuge. He could pull the wool over Kirito's eyes and at the same time worm his way under Asuna's skin (or panties if you will) so slyly, it was great!
The animation was fun and I do enjoy the use of Kokaitsu models in the cutscenes, something about them just lends to the NTR vibe.
The progression was also fantastic, with a bunch of NTR events involving and not involving Kirito, where you could stumble across a random woman being pounded by a street thug who appears to be a reference to another game's characters but also find Asuna or another female acquaintance being railed just out of view as to leave Kirito oblivious.
Shadow play, mind control, trickery, implied sex, stealth sex, sleep sex, this had it all! I was loving it!
And then, Part 2 came along.

Ditching the more open world vibe and going with a far more linear and heavy story centric path, the NTR becomes, as I like to put it, railroaded. You can't really miss any events unless you are purposely avoiding clicking on the heart symbols or inspecting the weird noises, and the choices become few and far between making Kirito seem less like an oblivious warrior and more of a hapless coward. Which breaks my immersion, since the Kirito I knew was anything but.
On top of that, Inoda, the mastermind, suddenly experiences a Metroiding and loses all his clout with Asuna. He was railing her in bed and had her slobbering his poll, but all the sudden she's back to giving him the shaft and Inoda himself is a blundering idiot who lets his dick do all the talking. Now it's Liz who has become the mastermind, with Inoda seemingly acting like an underling taking scraps from their master. Boo! Boo I say!
And the animations are very slimmed down, with the number of random sexual acts you can find being sprinkled in along the annoyingly long story driven paths, leaving my jerking hand high and dry. I come to fap, not to read a novel about Kirito's theory on how to fully integrate the human mind into the game. Sheesh.
Normally I don't review things unless I finish them, but when I hit the "fetch me a coffee Kirito" mission from the teacher, I was like "Oh gee, bet nothing untoward will happen to Asuna in the time I'm gone." It was so obvious, I could see the writing on the wall from a mile away. So I quit, I can't handle this dragging out anymore.
You fail to make a good NTR, when you have me wanting to root for the cuck.
