I bought a license for Corona once and according to my experience with it, it totally sucks. Air is better.
How about your game Tang, is it in the store now?
Well, uploading the textures to the GPU takes up most of the time. Starling initialization is just maybe 2 seconds. But if you upload an uncompressed texture of type 2048×2048, that takes on older devices 3-6 seconds.
on day 2 it is rank #2 in Germany and rank #3 in Austria in the word games category. That is a nice surprise!
Well, it is on the App Store now. However since you have an iPhone 4 / iPad 2 I recommend to wait for the next update. There are some memory issues that cause the app to crash on older devices. Got some terrible ratings cause of that already. 512 MB of ram is very little if you want to take advantage of Retina to the max (and 200 MB of these 512MB are already used up by Siri and the iOS).
Right tsafi, Starling is really big.
I hope my new game gets through the review this week. You have to have a look at it. It is technically the most advanced Air app I ever created using Starling extensively. Landscape and portrait mode support, 3 screen sizes (iPhone4, iPhone5, iPad), multi-touch, and three languages (English,Spanish, and German).
