Have no Idea How To Play & Website Has No Contact Support

The two things that aggravate me the most about apps here - No instructions so you have no idea how to use the app - or in this case, I have no idea how to play the game. I guess Im stupid but I have no clue. And then a website with no support and no way to contact the developer. I dont know how Apple keeps approving all these apps and these support links where theres no way to contact them for support. So for me, until they include some basic instrutions, this is useless
