dead screen not showing up after the jetfighter is dead. Should draw "you are dead" on the screen after the jetfighter's hp is 0
[Description] I have identified a bug in my shooter game where the dead screen is not displayed after the jetfighter's health score reaches zero. Additionally, there is no option to restart the game after the jetfighter's death. According to the expected behavior, when the jetfighter's health score reaches zero due to collisions with obstacles or enemies, a dead screen should be shown, indicating the end of the game. The player should then have the option to restart the game. However, the dead screen is not appearing, and the game does not provide an option to restart after the jetfighter's death. [Steps to Reproduce] 1. Launch the shooter game. Control the jetfighter to collide with obstacles or enemies, reducing its health score. 2. Continue reducing the jetfighter's health score until it reaches zero. 3. Observe the result screen and the availability of a game restart option. [Actual Result] After the jetfighter's health score reaches zero due to collisions with obstacles or enemies, a dead screen is not displayed to indicate the end of the game. Additionally, there is no option provided to restart the game. This behavior prevents the player from properly acknowledging their defeat and starting a new game session. [Expected Result] The expected behavior after the jetfighter's health score reaches zero is as follows: 1. When the jetfighter's health score reaches zero due to collisions with obstacles or enemies, a dead screen should be displayed, indicating the end of the game. 2. The dead screen should provide relevant information, such as the player's score and the option to restart the game. 3. The player should be able to restart the game, allowing for a fresh start and further gameplay.
