Sure, here's an example of a simple game where you can rotate a Minecraft block using Three.js library in a single HTML file:
This HTML file sets up a scene with a cube mesh using Three.js library. It also includes touch event handling logic to allow rotating the cube when touching and dragging on a smartphone screen. The cube rotates based on the touch position relative to the canvas.
Please note that you need an internet connection to load the Three.js library in the script tag.
