As an AI language model, I can help you with creating a simple game using JavaScript within an HTML file. Below is an example of a game that uses pictograms and can be played on a smartphone:
In this game, the player's goal is to click on the moving pictogram within a certain time frame, represented by a score counter. Each time the player successfully clicks a pictogram, the score increases. The game starts automatically when the page loads. The player can play the game by tapping on the pictograms represented by the Unicode characters.
