Smash the monster before they can invade earth. You won't win on your first try, but don't give up! The game seems easier and easier every time you play through it. Eventually, you'll be 5-clouding hard mode every time you play. Not insane mode though, it's nearly impossible (but don't worry, there's nothing it unlocks anyway) If a pattern is side-diagonal-side, hold the side button down through the whole pattern and just tap up or down when the diagonal one comes through. Same way for up-diagonal-up or similar patterns.
