Koi Rush is a reflex game built around a simple but brutal idea, control two fish at the same time. Your left thumb controls the white fish. Your right thumb controls the black fish. Obstacles fall, you dodge. One hit and it's over. Three Modes: -Solo — one fish, four lanes. The left side is dark, the right side is light. Your fish changes color as it crosses between them. Simple to learn, hard to master. -Classic — both fish dodge falling obstacles at the same time. Stay alive as long as you can. -Insane — the left side is flipped. Your white fish starts at the top while obstacles rise from below. Your brain will fight itself. Phase Meter: -Dodge enough obstacles and your phase meter fills up. Tap it to go invincible for a few seconds, use it wisely. Game Center Leaderboards: -Compete globally across all three modes. See how long you last against the world. Simple controls. No tutorials needed. Just tap and survive.

Drop Ball 3D's advantage is ratings volume (1.5K vs 1) and device support (3 vs 1). On price and ads there is nothing between them.
