Over healing baby ball production

This is the 'structural foundation' of the build. The strategy is to do a LOT of healing, don't let it go to waste, and shoot a bunch of baby balls with every heal.You only require a ' x ' ball to drive your passive combo, I usually try for a second ball for the fun factor. The passives are more important than a 2nd ball, but you could go for anything that makes baby balls, heals, or even damage if you feel like you need it. Baby ball production can be further maximized by adding either the / combo, or /. Evolving the into a would do more healing, which means more baby balls. So far my record is 41,121 baby balls on NG+, a youtube video link is below.
