Corona SDK is a cross-platform framework for building games, general purpose apps, and business related apps for iOS, Android, Kindle, Windows Phone, macOS, Windows desktop, tvOS, and Android TV from a single Lua code base. Lua is a fast and easy-to-learn language.
Pro Built-in physics engine
Physics are commonly used for apps that involve a simulation of objects that move, collide, and interact under various physical forces like gravity. Corona makes it very easy to add physics to your apps, even if you've never worked with a physics engine before.
Con Reduced flexibility
Corona's reliance on high level functions for expensive computations means that if the API does not provide what a developer needs, then writing a function to achieve that in Lua will result in a big performance hit. Even though this reduces the complexity of the actual code, it also reduces the flexibility a developer has on building their game.
