If you're having trouble keeping your comrades alive in the level 3 boss level - where you fight a Kraken - here's my solution. When you trigger the Kraken and have the main Comrade stand on the explosive claw button, continually direct (right click on PC) your comrades to the far side of the explosive barrel container, which should have a sliver of dock visible. None of the Kraken attacks reach there, and if you've got most of the other items found so far, you'll have no trouble surviving even if the Kraken knocks you out of position a couple of times.
