For a 4 year rework of a prologue, you'd think they'd have at least double checked that the grammar was correct. The simplest thing, (even for Dev's who's native language isn't English) is to make sure each word that's starts a new sentence is capitalized. In this case, the game is horrible for that and it's super annoying to read.
Sure, the graphics are stellar but the story is convoluted and makes little sense without explanation. Yes, you can puzzle most of it out but it's so complex with such a variety of characters that it leaves one to wonder how many decades it will take to make a complete story when there's that much detail. If it took four years to make this, I shudder to think of the wait for a playable game with actual sex scenes, an intriguing plot, and some sense of player agency to make significant choices.
If the Dev reads this, I have a piece of advice for him that I learned when taking a creative writing class that would definitely apply towards VN games. If it doesn't advance your story in a meaningful way, it's a waste of space. Not every book needs to be a Stephen King novel and not every VN game needs excessive detail. Otherwise you'll get slogged down in them and then your story will lag and the workload it takes to create anything of significance will become behemoth. Especially for a first game when trying to build an audience. From what little there is to play at the moment and with how long it'll take to get something worthwhile, it'll most likely become abandoned after a while of milk city for hopeful patrons.
In my opinion, VN games need to have way less characters so that the choices you make regarding potential relationships are more impactful while simultaneously the variety of scenes you get with each of them are of a greater multitude. Having too many characters means having fewer interactions/scenes involving the ones you may like. Unless, of course, you're a super Dev like DrPinkCake. He's made a ton of characters with a ton of content for each over 6 years. But there's not many Devs who can pump out that much content for that many characters and still have a great product.
Lose the unneeded detail. Streamline the story. And maybe there will be something here down the road. Good luck.
