Thank you for your detailed feedback! This project is a practice to test if it is feasible to build gameplay based on a story. That is the reason I did not write a long story with multiple branch storylines.
For the genre I think it is between narrative-based game and serious game. For future work or next project, to make a story more compelling, I will make more researches and even interviews to get related information.
Again, your encouragement means a lot to me! Thank you! :)
