So I've been practicing the early knockout glitch all day today and was even able to get 16 seconds as my fastest run. But after doing this for hours I still can't really find a consistent way to pull this glitch off. Does anybody have a consistent way to pull this off ? I've been doing full runs and this level always messes up my time because it takes 3 or 4 times before I get it sometimes even more.

hit the heart with 6 bombs then use the bomb special twice right next to it

Thank you I have tested this and it is way more consistent than anything I was trying.

You're welcome :)

Thanks god, i've found how to do it. Just, when the heart is black go right next to it, switch to bombs and spam your ex attacks:)
