Airdash Academy ep.07 - Movement Part 2
1. Projectiles and aerial attacks can be blocked without Faultless Defense, while grounded attacks must be blocked with Faultless Defense.
2. Ideally you'd want to move AROUND projectiles, but you can't run forward on the ground while holding the joystick backwards to block at the same time. But jumping DOES allow you to hold backwards to block as your character keeps moving.
