Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript. It can be played on a smartphone and incorporates pictograms for a visually appealing experience.
Before running this code, make sure you have pictogram images (`emozi_all/pictogram.png`, `emozi_all/princess.png`, and `emozi_rabbit.png`) available in the same directory as this HTML file. You can replace those images with your own pictograms or use appropriate images from the internet.
This game allows the player to control the hero using the arrow keys on their smartphone. The goal is to save the princess while avoiding the demon. If the hero collides with the princess, a congratulations message is displayed and the game restarts. If the hero collides with the demon, a game over message is displayed and the game restarts.
