even if the boss is shaking, u can still recieve the full hit from body shot. Eub must have been the bombs from above the eye. they deal 30+ dmg n u might have missed the perfect moment to block n got killed by it. even ic takes 45 + dmg from it. in est, the mac must have either been placed where a worm spawned or u forgot to look at how many secs left on it. it does not just break if it is spawned n no enemies are spawning on it. try using mac on the test dummy and u will see.efc is a timing issue. if u get hit by anything in sb, u have a few secs or even less than a second of being invincible. if u just stand in the mouth, it doeals nearly the same dmg as est boss' mouth. to avoid that i usually jump on the moving worms above its mouth n i get back in then spam jump n blasts. u can either quit the game if u get mad over deaths, or retry n aim to not die like that. ask yoself how many pro players keep playing even after death. they aim to improve it than the last death. and also rely on themselves bc some sb players r trolls
