Finally! The full version should be available for purchase within the next few days, pending some approvals.
The main app will become the full version and a paid product, and what most of you have on your desktops right now will become a demo. The demo will still offer a full 31 levels for free, while the full version has 111.
During Early Access, it'll be pretty heavily discounted.
You'll see another announcement once it's all live. Happy squaring!
