Sure! Here's a simple game that meets your requirements:
1 year
In the above code, the game starts with a 10-minute countdown timer displayed on the screen. When the timer reaches 0, it triggers the `celebrateWin()` function which plays a horn sound for 10 seconds and adds confetti effect to the screen for 10 seconds.
Please note that you'll need to replace `horn_sound.mp3` with an actual sound file for the horn sound effect to work.
Feel free to modify the code and add more features to the game as per your needs.
