Headcrush hits?

Normally the headcrush hits 4 times, even if you mash. I’ve heard there’s a way to make it hit a lot of times, does anyone know what this is?

Yup…you need to be at least half screen away, or catch your opponent at the end of a normal jump (so that they are riding on your head almost).

Mash for a full 8 hits…glitch him and that 100% life
