Revenge Master

Once I was the king of this country. My subjects revered me, and my enemies feared me. But one day my chief adviser betrayed me and, with the help of blackmail and bribery, managed to win over all the influential people of the capital to his side. They declared me a sorcerer, they slandered me! Not ashamed of anyone, they dragged me to the square and, to the accusatory roar of the crowd, dragged me to the gallows. I promised them to return and take revenge. Help the king take revenge. Kill as many traitors as possible and take them to hell with you before they get to you. How many waves can you withstand?
