The app it self is Oke. It loads slow which is not it’s best feature. There are many, many advertisements to buy stuff in the game, and to advance you most probably need to buy or be very, very patient.
The biggest issue is support, although you get a response quite soon (from fellow players) when the support guys from the developer kik in it’s end of the line.
I was attacked several times by a play who cheated (tweaked his game so his troops did not got get any damage) I reported this, but although it was very clear the developer refused to compensate the losses. When I asked why, they just did not respond, also not when I requested.
