Sure! Here's a simple implementation of a mini Mario game using JavaScript and HTML. This game can be played on a smartphone and uses pictograms for a visual representation of Mario.
To play the game, you can copy the above code and save it as an HTML file. Run the file in a browser, and a Mario game will be displayed. Use the up and down arrow keys to control Mario and avoid the mushroom obstacles. The game will keep track of your score, and if you collide with an obstacle, a game over message will be displayed with your final score. You can then reload the game to play again.
