Pawn

Goal: Survive the waves and defeat the king. Kill enemies to make the king laugh (laugh bar is yellow on top of the screen). 

After every wave completed the king loses a heart(hearts on top of the screen). 

Defeat all the waves to win, be careful with your health as well (bottom left on the screen).

Tip: If enemies are too far away and the fun bar is nearly empty, make the king laugh by hitting yourself by pressing H but be careful, it decreases your health. 

You can find items on the ground that might help.

Good Luck in the Circus.
