I dunno. I get the feeling the game is leaning a bit too hard on "it's a parody" as a shield against any kind of criticism of anything janky about it because "that's how it's supposed to be". The story is stupid, contrived and frankly ridiculous? "That's the idea!" The character models are uglier than necessary? "They're meant to be!" The characters are all one-note stereotypes (the Japanese sister apparently looks like she's 12 and has a tentacle fetish, because of course she fucking does)? "That's the joke!" The father character is such as asshole that I wish he'd just fucking drop dead already? "It's satire!"
I can't help feeling the story concept could actually produce something potentially rather interesting, but the developer doesn't seem to WANT to make something interesting, they want to make "incest-fuck and impregnate 23 female stereotypes just because, and tell a bunch of dumb jokes, anything else doesn't matter because it's a parody". I'll play along for a few updates at least, but I have a nasty feeling the concept is just going to get old long before we manage to fuck 'em all.
Look man, this isn't dadism, which tries to escape criticism by premptively declaring itself pointless. There is a point here, you just happen to disagree with it.
It doesn't arouse YOUR interest? That's fine, but since I feel that this is meant to be constructive criticism, I feel the need to state that there is nothing constructive about making criticisms based purely on your personal interests. After all, it's now what you do but how you do it.
And "incest-fuck and impregnate 23 female stereotypes just because, and tell a bunch of dumb jokes, anything else doesn't matter because it's a parody"? That CAN be made interesting. As in it being interesting doesn't depend on the approach, though that admittedly helps.
In the end, the question people have to ask themselves is: Is this enjoyable? Do I get anything out of this? And when making criticisms you have to make sure that if the answer is "no", that it isn't simply because it's not your cup of tea.
