Sure! Here's an example of a simple game where the scene becomes scarier as the player walks:
This game uses the device orientation event to detect tilting of the smartphone and keeps track of a "scareLevel" variable. As the player walks (tilts the device), the scareLevel increases, and new scary elements (represented by ghost pictograms) are randomly placed on the scene. The player's position is updated based on the device tilt. As the scareLevel increases, it visually becomes scarier with more ghost elements appearing on the screen.
