Sure! Here's an example of a simple running and jumping game implemented using HTML, JavaScript, and pictograms. Save the code below into a single HTML file and open it in a web browser to play.
This game consists of a player character represented by a picture, a ground, and the ability to run and jump. To control the player character, press and hold the space bar to make it jump. The player will fall back down due to gravity when the space bar is released. The game continues until you close the browser tab.
