In Pongo17, players represent godesses Midori(Nature) and Kuroyuri(Chaos), and they must defend their core crystal from a bouncing ball representing the original information. As they move their paddles left and right, they not only defend their crystals but also modify the original information of the ball. Along the way, they can collect power-ups symbolizing the different forces at play in this eternal struggle. These power-ups have varying effects and can tip the balance in favor of one side or the other.
