In some runs of 6-2 they play on violent with 100 health,they use pump explosion to go to the gate dealing 50 damage to them,then do an ultraboost and they go to Gabriel's piano without dying and leaving them with 15 HP left,how does that tech work??

i'm pretty sure that the core nuke explosion has 2 hitboxes for V1 and the inner one hits for 35, so just nuke closer to yourself and it should do 35
