For the first turns ONLY recruit recruiters until you have 20, then recruit builders to repair and then spies and firefighters to prevent damage. Put the rest into gatherers and workers. And then get your pilots much later when you have overwhelming numbers and 100% intelligence.
great idea, not fantastic implementation - why "ring on a star" - make that make more sense. needs undo. needs a way to measure distances - like a grid - the skill should be in knowing the order, not in the distances.
I found a simpler solution to last level 20 WITHOUT removing a ball, just make 1 blue ball- you only have to convert 1 ball to blue - it works about 60% of the time.
Halbeard is my favorite weapon, +30 melee damage, range=2 (ie I rarely get hit and I can hit through bushes), and high knockback. Much better than boomerang which is 8 damage.
