Ariel Sebastian Andres developed and integrated a role selection feature into the main game flow for the so1unp/2025-lab-05 repository, allowing players to choose between EXPLORADOR and GUARDIAN roles at game start. Working in C and utilizing ncurses for the menu system, Ariel refactored the color initialization and menu logic to use symbolic constants, improving code readability and maintainability. The work focused on enhancing the user interface and streamlining the game’s structure, laying a foundation for future extensibility. No major bugs were addressed during this period, as the primary emphasis was on feature delivery and code quality improvements.
