im currently on level 12, the last level of the hidden tomb. The only help i could give is to remember to look for the sandwiches. Two colours on either side of two balls of a different colour. If you have alot of room before the skull. Try to destroy the bomb ones more than the other special balls. If you get closer, switch to trying to destroy the slow motion balls. I've also found that if you play it in the window version, instead of the fullscreen option, it's alot easier to play the game because you don't have to move the mouse around as much, and that saves you precious time.
