Some levels really are hard to beat, though none are absolutely impossible! Don't give up and be careful when planning your strategy. Here are some general tips for you:

• Check the goals before the start of each level and try to collect the pieces you need first in order to complete goals faster.
• Take a good look at the game field before starting and plan out your first moves rather than making them at random.
• Try to collect as many pieces as you can in one move so you can get better power-ups!
• Combine power-ups to clear the field and complete the goals faster.
