I despise this game. I hope this crap gets thrown in the deepest, darkest, dankest corner in Guantanamo bay you could possibly find, then when his mind is just an inch from breaking, make him into crab cakes which I can savor every last intensely flavorful and violent bite
Here's my strategy for the Apocalypse Ciao Badge without using monkey cash. (I got it with 118 lives left). You will need a ninja monkey with upgrades (2,1), a mortar tower with upgrades (3,2), and a monkey apprentice with upgrades (2,0). First, buy a ninja monkey and put him at the bottom of the lava circle, as close to the circle as you can get it. Next, when you get enough money, buy the upgrade ninja discipline. After that, buy the seeking shuriken. Finally, get the sharp shuriken upgrade. Next, buy the mortar tower. Put the crosshair at the center of the circle. Buy the rapid reload upgrade, then the burny stuff upgrade, then the increased accuracy, then bigger blast, and finally bloon buster. Next, buy the monkey apprentice, put him at the top of the circle and really close to the circle. Buy the intense magic upgrade, and then the lightning bolt upgrade. That should get you past round 30 :)
