Sure! Here's an example of a simplified version of the Minecraft-like game you described, implemented as a single HTML file with JavaScript. Since it's a simplified version, it won't include all the features of the actual Minecraft game.
This game will spawn 10 randomly positioned blocks in a 400x400 box. You can control the player's movement using the arrow keys on your smartphone. There will be 5 enemies that will chase you, and if you get caught by an enemy, it's game over. Once you break all 10 blocks, you win the game.
