@ TobyCake - Cocooning means those larvae won't be used to make new units, but are available to be cloned. If you don't have enough larvae to get the max out of a round of cloning, you will waste that energy. It also lets you "save" some for upgrading territory units, which uses a LOT of larvae.
How to maximize "Holy Light" -
Turn on Mouse Keys.
Put one finger over the "5" and another over the "+" button.
Use your other hand to move the mouse.
Activate and tap like crazy!
I have an interesting situation. I have a laptop which I made sure to get with a number pad. I also have a secondary keyboard. If I turn on mouse keys, I can put one hand on the laptop and the other on the secondary keyboard and mine like crazy by pressing the "5" and the "+" repeatedly.
Great game, but the last one is a ROYAL pain! A hint button or some way to know you have at least ONE in the right place would be wonderful. Maybe in the sequel?
