Why is it that sometimes when you kill enemies on levels a huge gem falls through the middle of the screen...... This happens quite often but I have no idea why.... Does it have something to do with amount of bombs you use on the level? How fast you killed the enemy in? How many points you collected before you killed them? There has to be something that makes the huge gems fall.... I'm pretty sure it's not random... Does anyone have any idea? I've been trying to figure this out for so long!!! Thanks!!!
