Viking puzzle

Listen, listen! The Vikings landed and they were furious! Multicolored bricks block the way to their boat. The only way to get through is to smash them, but the more they hit them with their batons, the more bricks appear. It's up to you to mix colors. But beware: you have limited time to do so! An electric arc is coming towards you. If it hits you before the Vikings regain control of their ship, the game is over.
