BabySnake's tabular Q-learning exercise needs a small discrete state, not the flattened board encoding retro_gamer normally produces. Define get_state(game) in babysnake_env.py, returning a plain (agent_x, agent_y, food_x, food_y) tuple, and point babysnake's observation_function at it instead of declaring a character_set. Disable the on-screen state overlay so it doesn't clutter the terminal watch view.
