the least subtle money grab thus far on kong. it may be well made bar some linguistic work but it doesnt change the fact that you 'can' spend your gold on every turn.
as aronzei mentioned: support towers stack and the results are very impressive.
also, if you need more walls and happen to have a little too much cash, one can sell the wall factory and build a new one with a fresh cooldown. i finally made it to lvl30 but ima leave that for tomorrow ^^ gn8 & gl
had to give up at lvl20 8[ - air units only spawn in 'columns' where you have buildings; keeping it 'slim' can be much more effective. also, using 'walls' to make the path thinner and then using the distant places for anti air helps dishing out more dps as well. and remember to aim for the little tasks to upgrade them. later on (with achievements) support towers and 'spells' work nicely. but yeah... i still had to go through quite a few attempts. that said, i like this sort of challenge. could be 20% cooler if the tower (upgrades) descriptions were more precise and the difficulty would be ok if there were a few more achievements/challenges to help out.
