Probably not, it's years old now and a complete game already. If anything I'd think a sequel would be more likely.
....*sigh* When you are merely wishing for a sequel, please don't start your post with the implication that a sequel was actually announced.
If you make one please make it a paid premium app with no IAP. Please. Everyone here will be gutted for you if you ruin this series.
Before we get a sequel, can we have an update foriPhone 5 screensize? Pretty please? I also would pay for a bit of extra content, like new ship hulls, a few bonus sectors, alternate character skins, and new game modes. Again, pretty please?
How does this game play on modern devices such as the 5S and iPad mini Retina? Does the screen get black borders? Is the game still worth playing today?
It plays fine on iPhone 5S but you will get the black bars. The art was fantastic, so it still looks great.
If you bought this version for your iPad, you'd have to play in 2X mode, and there would be borders. There is a separate "HD" version for iPad.
iOS 8 Support for iOS 8 and all the new screen sizes is in the works, though the current build works, albeit with black bars. A sequel is also in the works. Stay tuned!
