About iOS support...

Publishing to the Apple App Store costs $99 per year you want the app up. Growtopia Music Simulator Final's code could very easily be run on iOS, I just don't want to pay when I'm done. Sending me $99 over PayPal is the only way I will ever support iOS. I'll make the small changes required to work on iOS and then publish it to the App Store as a free tool. It'll be removed from the App Store after 1 year if I don't get another $99, but anybody with a Mac will still be able to compile the code for iOS and put it on their device only.

Alternatively somebody else can do all the iOS programming and publish the program themselves if they want without paying me anything, of course. The code license allows it. (The license for the Growtopia assets require the tool to be free, though.)
