Mobile Game
Shoot the bombs!
This HTML file creates a simple game where the player controls a gun using their smartphone's touch screen. The objective is to shoot the falling bombs before they reach the player's location. The player's health bar armor and health bar are displayed at the top, showing their current percentages. When the player clicks the screen, a bullet (represented by a red circle) is shot from the gun. If the bullet collides with a bomb, the player's health decreases. The game ends when the player's health reaches zero, and they are prompted with a "Game Over" message.
