Worked fine until I did the update and now it gets me as far as the first attack and then buffers and the end. I would rate a zero if I could. Invested years and money into another App game and this is the same thing that I get from them. No time to invest in something that the programmer might not have time to invest to make sure that it works properly at least 95%of the time. Sorry if this is not you but after two tries and all I get is buffering my mind says run from it.
