I know it’s a common belief that the only way a shitty indie game can maintain an audience is to have a crappy lore, but how much more of a plot did this really need? Stop a girl from confessing to senpai by murdering her I’m the most grotesque way possible is all he needed to sell people on the concept back when it started. I think his over convoluting of the narrative killed interest just as fast as his inability to do anything right for over 6 years
Funny thing is a lot of the questions YandereDev set up for the lore to answer either don't need to be answered at all, or have a much simpler way to answer them.
"Why does every teacher know Martial Arts?"
Considering how the School has a Martial Arts Club, you could just use the excuse that they learned Martial Arts from visiting there a few times (Hell Alex even said that Raibaru was very willing to teach anybody when she was the club leader). That or just say they used to train at a Dojo that recently closed down or something.
"Why does the Headmaster hate children?"
I don't know if Alex knows this, since he was home schooled for most of his life, but it's fairly common for the principal or headmaster of a school to be a complete curmudgeon who despises children. That really doesn't need an explanation.
"Why do the police not do through investigations?"
Also doesn't need an explanation, people can just accept this through "Video Game Logic". Nobody questions why when you beat up a Drug Dealer in Grand Theft Auto, you don't see the police doing a through investigation and eventually showing up to your house with a warrant for your arrest. Besides, his reasoning for it is terrible anyways.
"Why does the Headmaster have a Stun Gun?"
Just say that he is either extremely paranoid, and/or he is extremely protective of himself. Either way, it's a simple answer that also adds a bit to his character. The same answer could apply to the Katana.
"Why aren't Ayano's parents around"
It's a common anime trope to have teenagers live by themselves, doesn't need an explanation.
The only questions I could think of, but couldn't think of a very simple answer too are the following:
"Why does Megami know who Ayano is?"
"Why is there a ghost in the girl's bathroom?"
To be honest, both of those factoids could just be removed. The former would actually make Megami a bit more believable of a character and a bit less of a Mary Sue, and would still make sense for a playthrough where you are killing everyone (I think it's reasonable for somebody to bump up security in an area where they know a lot of people are going missing and/or getting killed). The later should have happened anyways (Alex stop pretending you own Fun Girl).
