Just keep playing it. You will eventually find out what to do in certain situations. Also, save some bombs for the meteor showers which come after the 7th or 8th nuke.
To get seven minutes just wait until you get to the level with all of the red diamonds and just avoid them for the whole time. That's the easiest way.
