frameperfect

Frameperfect is a jump that can only be done when the player clicked in the exact frame needed. Frameperfects are one of the hardest jumps in GD. The first appearance of it was in 1.6, in a level Silent Clubstep by Sailent.

"Final destination contains a lot of frameperfect jumps which makes it insanely hard to beat."
