Sure, here's a sample implementation of the horror game using JavaScript in a single HTML file:
Time left: 10:00
This implementation sets up a simple horror game on a smartphone screen with pictograms. The game involves a green circle representing the player and a red dot representing the intruder. The player must press the orange button to hide from the intruder when the red dot is inside the green circle. The game has a timer set to 10 minutes, and the player must survive before the police arrive.
Good luck playing the game!
