Welcome to a new series of tips that go into more advanced techniques that can push survivability and scoring even further.
Starting this off, could you tell that there is a slight difference in speed between high and low elevations? If you did, you probably are already subconsciously utilizing it in your runs. The player helicopter moves slightly slower when on a low elevation. In addition, all bullets from the player and the enemy also move slightly slower.
Micro-dodging enemy bullets on the low elevation is, thus, a little easier. But changing elevations is still faster and safer if the high elevation has no bullet threats. Because traversing the game area is slightly faster if you use the high elevation, it can greatly improve your repositioning.
Now that you know this, utilize this in your strategy and use that elevation change to your advantage!
