ok, now that's BS.
I make an entirely unnoticeable parasite (i even unlocked all symptoms so that I could take them off) and when it gets down to the last part, the only country uninfected was Madagascar, after like 3 days of it bein spread to Argentina they sent no boats.
started in madagascar, infected everybody but america, had 2 random ships stuck in the atlantic ocean. my one thought is, why does a disease not infect a water supply just randomly, if the disease's waterborne/airborne?
Very original, good strategy, and I like the gem bomb too. Only bad part is the leading enemy problem (which you can fix by having plenty of towers around)
Retry day button needed BADLY...that day that I got $750, the next day I accidentally clicked and let go of the sling, so the thing just hit the ground. no money.
Doh...I just tryed again, and I *should* have finished on the 10th day, except I accidentally forgot I bought the E rockets with my surplus money, and hit up about halfway to space.
