Sure! Here's a simple running game implemented as a single HTML file using JavaScript:
🦁
This game allows you to control a running character by tapping the screen (on mobile devices) or pressing the spacebar (on desktop). The character continuously moves forward at a constant speed. The goal is to avoid falling off the screen by timing your jumps correctly. If you hit the bottom of the screen, a "Game Over" alert will be shown.
Please note that the use of pictograms is not possible without external libraries or additional code for mapping pictograms to Unicode characters.
