In what universe does the Unity Engine not play well with Android? The vast majority of mobile games I get from Google Play are done in the Unity Engine.There is no Android version of the game as the Unity Engine doesnt play well with Android as for a Mac Version there is a way to play it on a Mac which is described in the installation Guide attached if you have any difficulties ask the lads here and they will help you out
Now, it is quite possible that Man of the House would not be easily portable to Unity for Android or would just take too much time away from the Windows development, but that is quite different than blaming the engine for a non-existant problem.
