While I love the Protector Series, I liked having multiple map options. I'm at a point where I can only do Mountain Fire and it's irritating me. It'd be nice to do another map while I try to figure out my strategy.
In Level 18 the boss never killed any of my guys. I just kept throwing dragons, angels and guardians at him. Lame way to end, I was expecting a challenge.
After about 30 or so tries, I finally beat level 9! Woohoo! I had the full upgrades for life, damage, and earning cash. I had pockets of each pure color (3 at least by the end) all upgraded to level 6, plus a few confuse gomphas. All of my gomphas (or is it gomphi?) were in an area where they contact each wave twice.
