About the whole process and plots of the game

Dear author，
I hope this email finds you well. After running the project, I encountered challenges understanding the full gameplay mechanics, walkthrough, and win conditions. This makes it difficult to modify the game effectively while preserving its core design.
If possible, could you kindly share any available documentation (e.g., guides, comments in the code) or offer brief advice on how to approach the game’s objectives? Even a few pointers would be immensely helpful. I deeply respect your work and will ensure proper attribution in my project. Thank you for considering my request—I truly appreciate your time and generosity.
Best regards,
CYP

The issue names no files, tests, or entry points. Start by locating the game's main gameplay entry point and tracing its mechanics, walkthrough, and win conditions. Done means adding documentation or code comments that explain the full process clearly enough for someone to modify the game while preserving its core design.
