Great game. Play it everyday. Few small issues but works 100x better then it used too. Every once in a while, the screen just goes black. Then I have to restart the game again, then it is fine for a day or two. This never happens to an6 other app or at any other time. Only when playing game. Not sure as to why this happens though. Can't really screen record it. Never know when it is going to happen. When it does happen, can't see the screen at all. It appears to happen on any level.
