conversion of game to android.

I'm building a pretty simple game in unity free version but I may buy unity pro and the android addition. how hard will it be to convert the game to be used with the android? will I have to basically rewrite the program? how does that work?

  1. You will need to tweak your input (from mouse based to touch based and probably also include accelerometer)
  2. You need to tweak your assets (like less polygons, less textures, etc.) to get good performance on mobile devices
  3. Android version is still in development, but you eventually you can expect similar feature list as for iOS: http://unity3d.com/unity/licenses#iphone

recommand 1. unity asset store free sample
