The writing in this game is simply awful, there's no good way of saying it.
And I don't even mean the many grammatical mistakes, you can tell those come from English not being author's native language (nor is mine), and as such they can easily get fixed (and they do need to be fixed). No, the problem here is the dialogue and writing itself, it would be equally bad in author's native language or any other, even with perfect grammar.
The writing in here is worse than amateur level, most people can write better than this. Situations happen in nonsensical ways, there's no progression, passage of time is confusing, and god the dialogue is beyond terrible. No human talks the way these characters do. Everything is a caricature of itself.
The best way to put it in simple words would be, feels like a bad porn movie plot played by really bad and underpaid first time actors, wrote by a 14 years old boy who just discovered porn by watching an Italian porn from the 80s.
I honestly think author hasn't read a single book in their whole life. Should start there before trying to write something themselves.
