For the first map the best thing to do is build 4 Tack shooters at the corners,then you save up for a super monkey and TADA keep on buying tack shooters as the levels raise and use spikes to keep bloons from escaping.
Forget what others say,i think it is a really fun game.I like it because its almost like a classic shooter.Or what i played when i was about 9 or 10.
5/5 10/10 999/1000 reason 999/1000 is because you have to start over from the beginning when you die.For future games make checkpoints.Other then that i really like this and faved.
