The game itself is good. There were indeed a few crashes on my Kindle Fire HDX, but that's not that bad since the game at each arrival in a new system or on a new planet stores and you're back at the point before the crash after 2 clicks , I have the Options menu off sound and music and since then had no more crashes, this may as a tip ... The biggest drawback, however, is that the game has a lot of potential and actually a lot of fun, but I had to about 1 hour by !!! Perhaps I had luck because I flew by an alien transport system and close my target world came out, but that has already disappointed me. The game has at least 3.59 cost - overpriced for what is offered from my point of view!
