For this feature, I added a health system so the player has three lives instead of losing instantly. In nav_game.py, I added "health": 3 to the game state, and in spaceship.py I created a take_damage method that subtracts one life when the ship is hit. If the player's health reaches zero, the game ends. This change is important because it makes the game less punishing, gives the player more chances to recover from mistakes, and makes gameplay feel more balanced and fun.
