This spawn system is crap, it shouldnt be that frequent, I ended up fighting three spearmasters, a mounted spearman, and the sorcerer boss at the same time, now how is that possible?
***HINT***
If you beat a wave of bloons but it doesnt give you the option to move you can fix this by sending a wave of super monkeys across the screen (sent via the satellite structure)
The game really isn't that hard. If you're dying on the first floor then you're probably just spam clicking all over the place and not even reading your skills. So far I'm on the fourth floor and it's been pretty easy so far.
