Sure! Here's an example of a mobile horror game where you run and hide from an animatronic named Mister Smiles, implemented as a single HTML file using JavaScript. Note that due to the limitations of the text-based interface here, it won't be an actual interactive game, but rather a demonstration of how it could work. For a real game, you would need additional resources such as graphics and media files.
In this example code, we create a simple canvas-based game where the player (represented by a blue rectangle) has to avoid colliding with Mister Smiles (represented by a red rectangle). The `update` function is responsible for updating the game state, drawing the game objects, and checking for collision. The `isColliding` function detects collisions between the player and the enemy. `handleInput` is a placeholder for handling user input events.
Note that for a complete game, we would need to implement additional functionality, such as game levels, hiding mechanics, audio, and more. This example serves as a basic starting point for creating a mobile horror game with a first-person perspective and 3D graphics.
