So, has anyone figured out any way to avoid the final boss' 34000 damage bomb attack? It says someone needs to 'save' you, but hitting the chain thing doesn't seem to help, and there's no visible bomb to attack. Is the specific attack and the sprites it spawns simply glitched? Or is there something I'm just not noticing on the map that you're supposed to attack/do/not do to avoid that damage?

This. Even if you hit the chain free (I'm not even sure if it works or not. What part are we supposed to be hitting?) the person still blows up. Even worse, getting too close to a person who explodes and hit other people for 34000 damage as well.
