Sure, I can help you create a simple quiz game implemented as a single HTML file, using JavaScript and enclosed in script tags. Here's an example:
Note: The jumpscare implementation is left as a placeholder (`alertHisa("Jumpscare!");`). You can customize it by adding your own jumpscare sound or image.
When the quiz is run, it will display multiple-choice questions one at a time. After answering all the questions, it will show the final score. If the user selects a wrong answer, they will be jumpscared.
