Sure, here's a simple example of a text-based game resembling Minecraft, where the player can control an AI character using emojis. Please note that this implementation is very basic and does not include all the features of Minecraft.
By running this HTML file in a web browser, you'll see a 5x5 grid where the player is represented by a smiley face emoji "
😃" and the AI character by a robot emoji "
🤖". You can control the player's movement using the arrow keys on the keyboard. The player can move around the grid, and the grid will be updated accordingly.
