We have been using the Corona SDK by Ansca Mobile for some time now. Here are our top 5 reasons to choose CoronaSDK for mobile game development.
5. LUA is so much easier to learn than Objective-C
I won’t go into a lot of details, but a good example can be found here
4. Built-in physics engine, what’s not to like.
CoronaSDK used the Box2D engine so you don’t have to figure out trajectories, gravity, collisions, etc. Collision handling is relatively simple to do.
3. Multi-platform development for IOS, Android, Nook and Kindle Fire.
Get your games out to lots of devices. There are also Indie versions of IOS or Android only.
1.Lots of game templates and community support to get you started.
