How to get an easy perfect
Just before killing your stage boss, use your E-tank to refill your health back to maximum. Doing this will trick the game into thinking you've earned a perfect in the round. Once you kill your boss when your health is full, you will earn a Perfect.

Energy Refills after Boss Rematches
In the room in Seth's Lab where the 8 boss rematches are, there's a computer in the background with two large black and white swirling orbs. Simply shoot these with a charged mega buster shot and you will get a large health tank and a large weapon energy tank. After each boss fight, these same orbs re-spawn, essentially giving you a large health and weapon tank after each boss fight.
