Solitaire chess puzzle

I found this fun puzzle in a store, and I cannot figure it out! The rules to the puzzle are:

• All pieces are the same color
• Every move must result in a capture
• There must be only one piece left on the board when finished
• Pieces move as they normally would in a regular chess game
• Special moves (en pessant, pawn promotion etc) are not allowed

The puzzle had a special board with only 16 squares, but chess.com does not allow that in their diagram editor

 The diagram editor forced me to put two kings on the board, you do not need to capture them, only the black pieces.

Good luck!
