Sure! Here's an example of a simple game called "Parker" implemented as a single HTML file with JavaScript and enclosed in script tags. The game is designed for smartphone operation and uses pictograms.
In this game, the player's goal is to park their car in one of the parking spots. The game interface includes two buttons with left and right arrow pictograms for controlling the car's movement. When the car reaches the randomly chosen win position, a message is displayed congratulating the player.
