Similar to Burn Jumping in Blaster Master Zero 2, you can ride the momentum of an Aqua Shift by jumping at the right moment while leaving directional controls neutral. Unlike the Burn Jump, however, there is no way to keep that momentum without hovering. Once Sophia hits the ground, she immediately returns to driving speed no matter what. If you turn in mid-air, you will lose some of that forward momentum but you will not be thrown in the opposite direction. You cannot air brake by moving forward either. The timing window for this technique is weird: jump too early and you'll stall in place. It's best to jump after the Aqua Shift animation starts for maximum speed and consistency.
