Sure! Here's an example of a simple parkour game implemented as a single HTML file with JavaScript. It incorporates pictograms and allows gameplay on a smartphone. Remember to save the code as an HTML file and open it in a web browser to play the game.
In this game, you control a character represented by a filled rectangle. You can use the Arrow keys on your smartphone to move the character right, left, and make it jump. The objective is to navigate through the parkour without hitting the trees (represented by filled rectangles).
If the character hits a tree, it will fly up. If the character hits the ground, the game will end, and the character will be reset to its initial position.
