Device Timer Game
This game includes a timer that starts counting down from ten hours. If the device is turned off or the browser tab is closed, the timer will pause and store the elapsed time. When the device is turned back on or the browser tab is reopened, the timer will resume from where it left off, considering the paused time. Feel free to modify the HTML layout and styling to fit your preferences!
