Sure! Here's a simple implementation of a Mario game with new enemies and gimmicks using JavaScript and pictograms. Remember to save this code in an HTML file, and open it in a web browser to play the game.
This game has a game board with a player (Mario) represented by a pictogram. The player can be controlled using the right and left arrow keys. There are two enemies represented by different pictograms that move randomly up and down, and if the player collides with any enemy, the game ends and a "Game Over" message is shown. The player's position and game state are stored using the `style` property of the relevant HTML elements.
