You can save this code as an HTML file and open it in a web browser on your smartphone to play the game. Player 1 can control their character's vertical movement by dragging on the screen, and they can shoot bullets by tapping anywhere on the screen. Player 2's character will automatically follow the bullet. The game will end when either player reaches a score of 200.
