Just like Show Me Your Moves except with projectiles. Time pressing
to deflect laser bolts back at your attacker. Another option is like the trophy picture shows, when you get to the part of the game with the giant planetary ring and the tractor beam, you will collect the Laser Sword, which can be swung to reflect projectiles back at attackers as well, plus it looks way cooler.
Very rarely will anything die in one hit so make sure to be patient.
