Hello, this game is primary made for kids, so the interface is as easiest as possible, but there are 3 difficulties and I'm pretty sure that even adults would play this game to kill some time. You can install it on this link - https://play.google.com/store/apps/details?id=com.codsterrphotopuzzle.RotatePuzzle. Currently it's only for android, but I've been asked to make ios version, so I'll probably make it in next month or so.
