Oh, I just meant increasing initial population, eggs, and dumping. You can max out Overpopulate having 900+ Lipocytes just sitting on the plate.
It's true that Lipocyte eggs aren't something you use until more advanced challenges. But the principle is simple if you see it, whereas it can remain elusive for a very long time if you're searching for it and trying to figure it out on your own.
I haven't come up with an easy or moderate challenge though. It could simply be a Photocyte near a Lipocyte that needs more mass to split, then turns into a multi-cellular organism with Lipocyte eggs. But that’s just seeing the principle rather than using it -- which might be fine. Because it's something that, ideally, people should know about, one way or another, before going into challenges where they're crucial or necessary.
