If render quality was the only thing that mattered, or at least mattered more than the story - in a Visual Novel - then, yes, you would be right.
But since we (are supposed to) play these "games" for the story element over regular porn, I'd say criticism towards story should take precedence over criticism to visuals.
normally I'd agree with you but tbh I treat NTR / NTS games as something that is going to fall flat in story more than your average AVN. So in these type of games I feel visuals and animations are more important because of that. Tho I will say I am now getting into the story because of the dark element to it but im already prepared to be disappointed by it.
Still tho the criticism is about going to the beach even tho I have my own reasons where it can potentially make sense to me. But that just shows how ridiculous those events are if I have to come up with a reason with how they can make sense to me. Personally i think those events would of been fine if they were introduced in the next chapter or the 1 after.
I think it was just the pacing off them was off , since it's clear the beach event was planned for sometime. Which is what lead to the somewhat unrealistic reactions by Katrynn and Rebecca. I say somewhat because I can see one scenario where it can make sense but that assumes they both are putting on a brave face just to not worry anyone else and forget about it for a few hours till later and that is a stretch but it's the head canon im using lol.
