Heh. I don't think its _too_ hard with the right strategy. Focus on splitting big orbs down into tiny orbs at first (for more ammo). As soon as you split small orbs to tiny ones you can grab the tiny orbs quickly and they will be lined up on the same part of your GlueFO. Then if you shoot medium orbs with this concentration of tinies it will split it down much quicker to more tinies. Also don't worry about health at the start of the challenge - just go straight for generating tiny orbs! Good luck ;)
