Bug 803

[Description]
I am encountering an issue with the health score display and update functionality in my shooter game. When the player's jetfighter collides with enemies or obstacles, the enemy's blood should be shown on the screen, and the health score should be reduced accordingly. However, the health score is not currently displayed on the left bottom corner of the screen, and there is no visible indication of the health score being updated when the player's health is reduced.

[Steps to Reproduce]
1. Launch the shooter game.
2. Control the jetfighter to collide with enemies or obstacles.
3. Observe the screen for the health score display and update.

[Actual Result]
After colliding with enemies or obstacles, the health score is not displayed on the left bottom corner of the screen. Additionally, there is no visible indication of the health score being updated, such as a decrease in the displayed value or any UI elements indicating the health status.


[Expected Result]
I expected the following behavior to occur:
The health score should be displayed on the left bottom corner of the screen throughout the gameplay.
When the player's jetfighter collides with enemies or obstacles, the health score should be reduced accordingly.
The updated health score should be visually indicated on the screen, either through a decrease in the displayed value or through appropriate UI elements reflecting the health status.
