Inversion

Clear the way for the green balls controlling Prot to absorb the blue balls. It won't be as easy as it seems, cause the controls are inverted. Keep your finger on the controller to direct Prot (red ball). If you double tap the controller Prot will emit a wave that will finish the blue balls for an instant, but be careful, because they reappear really fast... so fast that it may not be such a good idea to use it. You can emit three waves, and by doing it Prot will reduce its size. Some blue balls become red when they completely appear (they will look like Prot) and that will allow Prot to increase its size as it absorbs them.

Have fun!
