Sure, I can help you create a simple game using JavaScript within a single HTML file. Here's an example of a game where you'll need to press a button within a specified time limit:
Explanation:
- The game starts with a timer set to 10 seconds and a "PRESS" button.
- When the player clicks the button, it checks if the game has started.
- If the game has started, it stops the timer, disables the button, and displays a "You Win!" message.
- If the timer reaches 0, it stops the timer, disables the button, and displays a "Game Over!" message.
You can enhance this basic game with different features and graphics based on your requirements.
