Well, if I'm being completely honest, I'd say that's a hyperbole. Guess I'd categorize this as shit-class "NTR" - like how an overhorny virgin preteen would think of NTR.
It's frankly, ridiculous. The conversations, heck, the whole script is stupid(-adjacent), and I don't think it is the MTL's fault.
The ladies are nicely generated AI CGs, though, and the animations are passable (even if they clearly reek of lazyness). The gameplay gets tiresome really fast, too - yes, you should use Cheat Engine/mtool/something along the line.
