Here's a quick look at the mechanic you'll need to go through to access the birth.
The core element is pretty simple: click on the orbs before the orbs click on you.
You'll have to click on a specific amount of these to get the power to go to the first stage, then the second, and then the third.
The balls will become faster and faster with every stage, and if they touch you you will lose a percentage of your power until you go back to 0 power.
Once you clear a stage and progress with the birth for that stage you will not go back if you hit 0 so don't worry! I'm not that cruel :^)
The core is subject to change, and it surely needs refining, but as it goes this is a solid mechanic to start with.
It's also giving me a chance to work with pathing in AS3.
I'm also programming this in mind to be converted to HTML5 and JS, so I'm hoping to have that out a few days after I finish the flash version.
