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.

If you need more E tanks to beat the game. Just let the timer after you die hit 0, go back into the game and you will have all the tanks you previously collected and you can recollect the E tanks from the levels all over again. I got 10 E tanks at one point.

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.
