Sure, I can help you create a simple scary game using JavaScript and HTML. Here's an example of how it can be implemented as a single HTML file:
In this simple game, the player wakes up in a dark room and is given choices to progress. The game uses JavaScript's `alertHisa()` and `confirm()` functions to display messages and options. Depending on the player's choices, different outcomes and game over conditions are triggered. Note that this is a very basic implementation, and you can add more features, graphics, and interactions to make it scarier and more engaging.
