The drag and select option makes this game wayyyy too easy.

Pretty easy once you realize the cpu won't attack you right away. Go for the '8' nodes to build up your forces. Don't bother attacking the cpu early unless he has only a couple men guarding a node.

Don't attack the hidden levels until you reach at least level 50 and have upgraded most of your skills to the max. 5/5

1.15 million! 50/50 yellow (no red) Needs more songs and levels, but very nice. 5/5

I don't know if anyone has done this, but I just beat 'easy' level with only two squirt towers.
