Beat game, I found 10-11 liposomes, 50 slicer enzymes, 8-9 defenses, that's 50% should defeat any virus in the game with a little bit of DNA repair for the infester. Most of the time you want to two chlorophyll and two mitocydria. Make sure you have enough of those green blobs to stop the free radicals.
Lv.6 seems really difficult. I built up lots of splicer enzymes and defenses, and then my nucleus gets infected and I run out of ATP and lose. I'm giving up.
