it's a cool idea to have the mc becoming a professeur but it is not well executed, you go to fast on yours story example in other story it take 1 chapter to die and meet god another one to state is whish and a little bit of world building and another one to start is adventure and you did all of this in one chapter and not even a long chapter.
And because you have little to no spacing between major event in your text you can miss major information like when i first read your first chapter i totally miss the part where he talk to god
Your story can be a good one because you know what your mc want to do all you need is to dilute your story to not have to much information and a little bit of “mise en page” and your story can be awesome
