This walkthrough is pretty brief, yes, as my intent wasn't to give full description of the story, but rather point on other possibilities within the story (a lot of people complain that the game feels linear because they get locked on their route very early).
Note that our current cast of characters is not final, I'm planning to change a lot of stuff in one of the future updates, so don't feel like you're cutting yourself from anything, you will be able to change your fate.
As for pretentious style of writing: that's Blake's personality
And it's gonna change with his progression towards femininity as well.
I'm sorry that you didn't like it. Can you give me examples of errors? I would like to fix those.
