Okay so when playing multiplayer with your friend player 1 has to have the rock-throw ability and the other has to have the roll ability. When player 1 picks upp the rock player 2 starts charging up the roll on it. When player 1 has trown the rock and it's about to hit the ground player 2 rolls. This strategy is so op if paired with a growth ray to make more platforms stuck together. It's almost a guaranteed win. Thanks for reading this please drop a like.
