This Python-based console application implements a classic word-guessing game where players attempt to uncover a hidden word by suggesting letters within a limited number of attempts. The engine features automated secret word selection from a predefined library and dynamically calculates the number of allowed mistakes based on the word's length. The system includes robust input validation to ensure only single alphabetic characters are processed and maintains a real-time display of guessed letters and current progress. By managing game states and terminal feedback, the project serves as a practical demonstration of procedural programming, string manipulation, and user interaction logic in Python.
