Outstanding problems

Informations or whatever

First, excuse my grammar, English is not my first language so if you find something wrong please inform me.
Second, I'm writing a book irl (wanna publish) so tell me if there's something you think could be improved. Don't try to be nice, I want your FULL honesty.
Third, it'll probably take me a while to actually finish a chapter. I'm only publishing it right now for feedback (I haven't finished the first chapter yet), so i will apologise in advance if it tales too long for updates.
