Controls Watermelon: arrow keys=move. m=throw. Banana: w a s d=move. q=throw. Coffee: i j k l=move. p=throw. Bacon: f c v b=move. g=throw. red banana, red eggplant, red ice cream and blue sushi are not a part of the gameplay. I just could not find a backdrop without players.
Thank you to cranky watermelon for creating the amazing video game sensation "boomerang fu"!
