Here's an example of implementing the game you described:
In this game, the player is presented with a pictogram of a door. They need to click on the door to see if they survive or die. The flash (survival) is automatically activated after 5 seconds, and if the player clicks on the door while the flash is active, they survive and win the game. If they click on the door before the flash is activated or after the flash has expired, they die and lose the game.
Please note that the actual implementation may vary depending on the specific requirements and design choices.
