Sure, I can help you create a game where a 10-year-old boy named Lithish can swing freely like Spiderman. Here's an example implementation as a single HTML file using JavaScript and pictograms:
In the above implementation, we have a game container with a background image representing Lithish's Spiderman adventure. The player is represented by a pictogram of Spiderman. Lithish can swing up when the user touches the screen and stop swinging when they release.
You'll need to prepare the actual pictogram images for Spiderman and the game background and modify their file paths in the code (`emozi_all/pictogram.png` and `emozi_all/chicken.png`). Additionally, feel free to adjust the swinging speed and height by modifying the appropriate values in the JavaScript code.
Remember to save the pictogram images and the HTML file in the same directory on your server or device for the game to work properly.
