For u guys who have trouble with the lvl 14 wave 50 ninja, hes really easy. use shift-click and nuke him with 5 fully upgraded fireballs. Then build 5 temples really quick to get the mana to hit him with another
personally i thought the challenge map was insanely easy. I just put my first 5 points in damage, next 10 in rate of fire. then from there for every 5 points id put 2 in damage and 3 in rate. i ended the game with 11 damage and 18 rate of fire and easily cleared the boss stage -__-
