Build a timer Widget

We need to design a timer widget for a game(bomb attack) which should have the following features. 1. When we start the widget by default it should start with 10 minutes timer ( should have a feature in setting to change this default time to any other number in minutes ) 2. There should be a start button. One u press it should turn into a Pause button 3. There should be + 1 min + 2 min -1 min and -2 min button on the screen in timer to add or subtract time while the clock is running 4. If the timer moves in last one minute, the screen should start flashing in red color( changeable from settings) and should play a sound repeatedly for a minute (changeable from settings) . This tells the person that this is the last minute to defuse the bomb and creates urgency. 5. In case he fails and the timer goes to 00 then a blast sound should be played ( changeable from settings) and screen should show a message in large red fonts “ ITs a blast” and at the bottom, there should be Restart button which will restart the watch. 6. Additionally, there should a defuse button on the screen once the timer is started if someone presses it to mean the bomb has been found and deactivated. The screen should show in green’ bomb diffused’(should be changeable in settings) and should show restart button 7. Other settings should include change of background color of the widget app
