Free Health Restore (certain levels)
On levels where you can fall off the stage and get rest to a nearby continue point: Activate the continue point with at least your ninja berserker power charged up, now activate your ninja power (anyone that restores health will do), jump in the pit, you will be reset to the save point with more health than you had when you got to the continue point, and your ninja power will be charged again, use it, jump off the stage, repeat till, you are full except for the bit of health that you normally lose for falling.
