I am with a project considering to use Unity for releasing our game on iPhone and Android.
Our game is pure 2D and we want one uniform project to push to both platforms: What kind of problems can I expect? Does anyone here have any previous experience in this matter?
There should be no problem with a platform switch as you can choose your wanted platform under the build settings (file->build settings).
You should know that you can only build iOS versions on a Mac! Dont’t know if you could build Android versions on a Mac though, but in our firm we have a PC for the Android build and a Mac for the iOS builds.
You could use the same project for both builds and only have to change the build settings!
