Acceleration in water will be very useful in KZ. The acceleration in water must be on the water surface to be effective.
Specific operation: keep pressing the space in the water, first press W to accelerate and then release W, press A to shake the mouse to the left (45 degrees is the best), and then press D to shake the mouse to the right. The speed is directly proportional to the synchronization of your keyboard and mouse. If you add it well, the water speed can reach 300+ (the speed of walking on the ground with a knife is 250)
