As an AI language model, I can help you with the code for a simple game where you control a character (represented by a poop emoji) using smartphone operation. The game will be implemented as a single HTML file with JavaScript enclosed in script tags. We can create a basic game where the character moves and avoids obstacles.
Here's an example code that you can use as a starting point:
In this code, we have an HTML structure with a game container (`#game`) and an image of the character (`#character`). The character can be moved using the arrow keys on the smartphone.
You can replace `"emozi_himawari.png"` with the path to your poop emoji image file to represent the character. Additionally, you can modify the `moveDist` variable to adjust the movement distance of the character.
Note that this is just a basic example to get you started. You can build upon this code and add more features, obstacles, and gameplay elements to create a fully-fledged game.
