First of, they still "cum-sucking abominations", even if each of them have...what, quantum physics, AI and abstract mathematics PhD. Game literally builded around it.
So are MGD and MGQ. What's your point?
Second, that was cruel for a boss to kill its subordinate. Like, really? She have inexhaustible amount of 'soldiers' to do so?
I mean, the barghast and lampas are effectively frontline infantry so yes, it's likely that the boss has plentiful more soldiers to throw at the world. Also, every cruel dictator throughout history has practiced a similar methodology of handling insubordination. The Red Army was infamously liquidated and re-organized under Stalin's regime, to great effect.
Third, that was dumb, to refuse to attack me when her boss definitely not in a good mood. Put at last some fight to save a face and life. She brave, but also incredibly stupid.
I believe in the genocide route, you've demonstrated numerous times over that you can easily handle the entire lampas species. Being given an order to effectively commit suicide seems fairly unreasonable. On the other end, the PC has shown compassion for the lampas in sparing them. As far as that one lampas was concerned, you weren't a threat, let alone someone who would get in the way of their plans unless it directly impacted you.
Fourth, game tries to make me feel bad for it. Why? It was her personal decision to do so, nobody forced her doing it with a gun at her head.
Is compassion for someone showing you mercy at every turn a foreign concept for you?
Fifth, what was it all for? Just to show up that they not only a "cum-sucking abominations" but they also have feelings? Again, I get it long before this scene.
The point was to establish what the outcome of your kindness or cruelty can result in, but also to put forward just how cruel the end boss actually is. It establishes the stakes for those who oppose her, gives your character motivation to get stronger, and establishes the lengths the end boss will go to in order to dissuade "wrong think" within her ranks. In terms of narrative elements, it's as basic as MGQ was in presenting to you the flip-side of Human/Monster relations when rape wasn't a factor.
Game is just dont work for me.
Yes, art is good....well mediocre, okay.
I mean, if you're jerking it to Shrift...
Yes, story is good...maybe a little bit silly.
Yes, world building is good...again, silly in some concepts but meh, moving on.
Like I said, the story is basically Undertale except with porn. The world-building is fine, nothing to write home about.
Gameplay? "Default" RPGM kind of gameplay, nothing to hype on.
Porn part...makes me laugh several times but overall 'gud enuff'.
But overall it tries to do thing that does not work for me, like
If it doesn't work for you, it doesn't work. I'm not trying to twist your arm. I just think you gave up too easily and expected something that the game never implied.
I already know that. Is there are more than that to it?......No?! In trash bin than.
There is a lot more. It's up to you to make the effort to find out what that is, or not.
Well, no. Undertale was "an ordinal rpg that not so ordinal at all...more on that next". Whole game was builded on it.
Like EXP was was abbreviation for EXecution Points, LOVE for Level Of ViolencE, etc. That why it worked. And yes, undertale is JUST an interesting game, not a masterpiece GOTY 12 out of 10
And what we have in "blue shrift"? Ehhh.....demons are not evil?! First of, its debatable...I mean they all womans, which is...but anyway, is that all?!
Okay, so I'm going to pretend there was something beyond casual sexism for your last sentence, and focus on the fact that Undertale wasn't operating too far outside the normal mechanics of the rpgmaker engine in itself. It simply did what games like Shrift and MGQ

aradox do, which is manipulating certain elements in the engine for a desired mechanic. I'm not a dev myself, but I imagine I could get the same results as Tobey did if I made the investment. The mechanics all apply numerical values to certain behaviours, which involve "if" and "when" triggers.
I can tell you that you're wrong about the nuances of Shrift's demons on the basis that I'm playing it, have passed the section you quit at, and have paid attention to the story. There is a lot more than "demons are evil, except when they're not." I would personally discourage you from making broad statements on a game you know nothing about based off your limited understanding of what some random on the internet says. Obviously, I'm not giving the full details for reasons of not spoiling those who might want to play it for themselves.
