Fun fuct: You can actually get the badge using pacifist mode. Add no death bombs and all the attack handicaps, add bullet speed and heart cheats and you can slow-mo dodge them bullets with five lives, still getting two stars. Olé this badge!
Badge guide: 1st level - collect energy, build up combo, don't lose no segment. In the upgrade menu max out armor. 2nd level - you will get first blades bonus and then armor, but don't fight with the bug, just avoid it. Next you can upgrade whatever you want, but stamina will be useful. 3rd - press space as soon as you hear explosion - that indicates purple guys spawning. Play it safe. You will get invincible bonus, use it, and when there's one second left, use the bomb for cautious. Repeat until it's over. 4th level is the hardest - just try to avoid the enemy, use your stamina, but if you fail one segment, it's cool, I made it even though. Armor will give you three hit protection from energy balls, so when you get blades at this level, just switch them back to armor. At 5th just stay in the middle and gather energy moving horizontally. Use stamina to avoid eventual collisions. Next level is just a matter of colecting couple energy balls and you've got yourself a badge. Hope it helps!
Ok guys, how to get badge even without the best gear? During the match, you can quit every hole, and then re-enter it without penalty time or something. Just click the door in the bottom left, and then start match and continue. You can use it to find the best path for your ball. I used Run, Airboost and Stop power-ups and finished every hole in about 30 seconds. Good luck!
