In October 2025, Georgy Schulgin focused on stabilizing core gameplay mechanics for the fossguild/naja repository, addressing a critical issue in game state management. He corrected the get_free_cells_count function by ensuring apples were included in the occupied cells calculation, which improved the accuracy of free cell tracking and overall game logic. Schulgin refactored this function to enhance clarity and maintainability, aligning with project standards and supporting future feature development. Working primarily in Python and leveraging his skills in game development and state management, he delivered a targeted bug fix that reduced edge-case errors and enabled smoother progression for new levels.
