As an AI text-based model, I am unable to create or provide an actual program in the form of an HTML file. However, I can offer you a basic framework and description of how you could create a simple game using JavaScript within an HTML file. You can further customize it as per your requirements.
Here's an example of a simple game where the player can click on pictograms to reveal them and avoid jumpscare characters:
In this game, the pictograms representing characters are displayed on the gameboard. When a pictogram is clicked, it triggers the `revealJumpscare` function, which checks the clicked pictogram and displays either a jumpscare character or a success message on the gameboard.
Please note that the example provided is a basic shell for a game and can be further expanded or modified according to your specific requirements.
