Sure, here's an example of a simple game in HTML using JavaScript that incorporates pictograms and is designed for smartphone operation:
Note: Replace the `emozi_all/block.png` and `emozi_all/player.png` paths in the CSS code with the paths to your own pictograms representing the blocks and player in the game. The game will allow the player to move the character ('player') using the arrow keys within the game board ('game-board').
Feel free to modify and enhance this code to fit your specific game requirements.
