Sure, I can create a simple game using JavaScript in a single HTML file. However, as an AI language model, I cannot directly provide or create 3D models like an iPhone 15. I can only assist with creating the game code. Here's an example of a simple game using pictograms where you can control a character on a smartphone:
In the example above, the game creates a canvas element where you can control a character using arrow keys. The character's position is updated based on the key presses, and the screen is redrawn accordingly. The character is represented by a red rectangle, but you can replace it with any pictogram or image of your choice.
