Nao’s hat is missing several monsters so the only way is to play this original Arkanoid clone and return them back.
When I say one really good clone, I mean really good. In The Nao's Brick Challenge you control mustaches which bounce balls into different bricks and sometimes, you collect bonuses. But this isn’t the end. Sometimes, the bricks are not stable and the bosses are fun to fight with. The surprises are everywhere. The difficult is well-chosen, not easy or hard gaming.
