Sure! Here's an example of a horror game set in a toy factory, implemented as a single HTML file with JavaScript enclosed in script tags:
👻
This simple game sets up a toy factory horror theme. The game area is a square div representing the toy factory. The player controls a ghost avatar (represented by the
👻 emoji) using their mouse on a smartphone or desktop. As the player moves their finger or mouse, the ghost moves accordingly within the game area.
Please note that this is just a basic example demonstrating player movement. You can expand and enhance the game by adding more features, levels, and game mechanics according to your requirements.
