Kraken tips: Take out the four little guys with fully upgraded fire shots. They might take a second round of ordinary cannonball to finish off.
Then keep your distance from the center and keep on firing normal shot. Try not to worry about dodging. You will get hit a lot, just focus on hitting your targets.
