Here's an example implementation of the game you described using HTML, JavaScript, and CSS:
😄
You can save the above code in a single HTML file (e.g., game.html) and open it in a web browser to play the game. The game will randomly change the emoji every second, and every 10 seconds, something weird will happen based on the provided commands: "PARTY" changes the background color every 0.5 seconds, "more emojis" adds more emojis every second, "why is it raining" adds rain emojis, and "different texture" changes the emoji to a rainbow square or a ball every second. After 10 seconds, the weirdness stops, and the game resets to its initial state.
