Sure! Here's an example of a simple game where you are on a train and something strange happens. The game is designed for smartphone operation and uses pictograms. It is written in HTML and JavaScript, enclosed in script tags. Please note that this is a simplified implementation for demonstration purposes.
Strange Train Journey
In this game, you start on a train and move from one train car to another by swiping left on your smartphone screen. The train cars are represented by pictograms, and each car has a specific symbol. When you reach the "strange" car, an alert is shown indicating that something strange happened and inviting you to solve the mystery. Note that this implementation is a basic skeleton and can be expanded upon to include more gameplay elements and interactions.
