Sure, I can help you create a simple game using JavaScript enclosed in script tags within a single HTML file. The game will be compatible with smartphone operation and will use pictograms if possible. Here's an example:
Simple Game
In this example, the game area is a 300x300 pixel div and the player is represented by a pictogram (represented as 'emozi_all/game.png') which can be replaced with your own pictogram image. The player can be moved using the arrow keys on the smartphone's virtual keyboard.
Please ensure to replace `'emozi_all/player.png'` with the correct path to your player pictogram image.
