I'm an independent iOS developer. My paid apps have sold over 100,000 copies at 99¢ or higher. In total, my iOS apps (including free apps) have been downloaded over 7 million times. I took a look at your app in the App Store. Here's your problem: your icon. The icon is the most prominent thing the user sees when first looking at your app in the App Store. Change your icon, and you'll get more downloads. Trust me :-)…
The Icon is bad, the copy is bad, and the name is bad. A factory? I have trouble associating factory with anything fun. Call is something like Ball Crusher, sounds more fun.
This is my stupid opinion, and I could be wrong, but try to make the copy more fun, leave the technical explanation to later. Most people only read the first few lines anyway. Get a simple icon, don't try to convey too much info. Just have a colorful ball on a nice background.
Oh, and thanks for putting yourself out there for criticism, is help you and us all. There are some great ideas in the thread, and the game looks like fun.
