Loved this game when I was able to play it but sadly I can no longer download the controller app from the app store and that means the game is NO LONGER PLAYABLE. No one has created an alternative to the phone and I doubt anything will happen since it has been years. Super sad but it was a great concept when it worked.

You can still get the controller apps online, google is your friend. Unless you're on iphone, if you are then lesson learned i guess... screw iphone. https://eon-altar-controller.en.softonic.com/android

Do not buy! the required smartphone app has been delisted, so you can't play this game at all anymore.
