[b]THE MORE critters YOU KEEP ALIVE & THE quicker YOU BRING OUT THE next level THE bigger the SCORE YOU WILL GET... eg. KEEP MOST OF THE FIRST 3 LEVELS ALIVE AND THE 4th WILL GIVE YOU ABOUT A 100,000 WHERE AS IF YOU KILL EVERY ONE OF THE CRITTERS FROM LEVEL 1 TO 3 THEN BRING OUT LEVEL 4 YOU'LL ONLY GET ABOUT 10,000 OR LESS...THAT'S HOW I CAN GET ABOUT 80,000 ON EASY MODE BY BRINGING OUT ALL 3O LEVELS HAVING ONLY KILLED A FEW CRITTERS ALONG THE WAY...THEN WHEN YOU DO KILL THEM ONE BY ONE EACH KILL IS WORTH HEAPS MORE ...IF I KILL EACH LEVEL ONE AT A TIME I CAN ONLY GET A FEW MILLION ...have fun
