You can also perform a maneuver called roll. By holding the roll button, your ship will hastily spin around.
Rolling will dramatically increase the rate at which you will gain energy but it will slow down your ship quite a bit.
Rolling in tight spots can turn to your advantage, because apart from the extra energy, it might help you to cope tight bullet patterns more easily.
Much of the advanced game strategy is tied around the roll maneuver; in order to conquer Sylph Wind, you must know when to roll and when to move quickly.
You can also ram enemies while you are shielded; this is called invincible contact. Whenever you destroy an enemy with an invincible contact, you are granted with an instant energy bonus.
It means that you can also level-up by using invincible contact apart from scratch.
As you can see, there are two important sections around
the ship. The weak spot, and the halo.
Everytime an enemy bullet is within the halo, you are scratching and will gain energy.
But if a bullet comes in contact with your weak spot, you will get hit and lose a life.
When you are shielded, for instance after a level-up, you can point-blank enemy bullets over your weak spot and rapidly get loads of more energy. You can even re-fill your energy gauge before the shield decays and gain a new level-up.
Gaining level-ups while the shield is still active is called level-up-chain. This is one of the main methods of getting high-scores in Sylph Wind. Please refer to Scoring Mechanics section for further details.
