The day has arrived: Corona Enterprise is now free too!
Now it is just one Corona.
Integrating with native C/C++/Objective-C/Swift/Java code is now available to everyone. I’m sure a lot more developers will be developing native plugins that are sold (or for free) at the Corona Marketplace.
Corona and Lua are the best combination of simplicity, speed, stability, size, deployment choices, and community support for 2D games and app development. (No, I don’t get to paid to say this, I’m just a long-time user / developer.)
