The Little Monk Lite

This is a Lite version, more complex and fun levels can be found at the full version. Below is the game description:
It is yet another snow season. Look at the beautiful snow on the surfaces of hills. The temple where little monks live is bothered by some strange yellow bugs all around. It is really difficult to kill them because they are hidden everywhere and their body color are so similar to the wood. Luckily, Little monks get a big magic snow ball from their most admired old monk, and could now start the long-waiting battle with the bugs. Each battle is different, and little monk has to fly above the yellow bugs and drops the ball. While, the big snow ball can transpass any obstacles magically but does not hurt little monks in any circumstances. The little monk only has 10 opportunities to get the chance for saying Goodbye to all those bugs. However, yellow bugs are also smart guys, how will they protect themselves in this endless game play?
