Very very neat idea, even if this entry didn't show off the full potential of this mechanic I really like what you're going for here. I think to really push the player in to engaging fully with the glob mechanics, perhaps each glob can have both a positive and negative - even if it's just something like the more globs you have attached the slower you move. That way the player is more frequently making decisions on whether or not to keep globs or throw them.
I really hope you continue fleshing this out post jam!
