Butterfly Arkanoid

Once upon a time, there was a beautiful and happy country named Butterflyland, where all butterflies were gay and free. The land was blessed until evil greedy dwarfs came and shattered peace and quiet of this place. The evildoers captured all butterflies and immured them in mysterious dungeons, built of heavy stone blocks. Now all butterflies are sad and pray for help. Can you destroy all blocks and save butterflies?
