I love the story and the implied meaning of it. It is inspiring in the ending choice that all the choices lead to a good ending. On the other hand, maybe some bad endings can be helpful in the story, like providing choices to represent the evil thoughts of the character, like stealing the scripts and publishing them in his own name, and lead to an ending that he gets some money and fame at first, but he cannot do anything as well as or better than that, so people would find out the plagiarism and he loses everything.
I like how the choices lead the audience gradually to know the story, knowing the story while exploring is like a puzzle game. The negative side of it would be little risk of each choice. It's just personal!! I prefer something with more emotional fluctuations.
The images you plug in are so great! If you want to explore more, some variables might be interesting in the game. Like a numerical variable of the number of items that the player has invested, something would used in puzzle games often,,. :-))))
