Sky Force is one of those games that’s really easy to play in short bits, but it’s entertaining enough that you can play for longer stretches. It’s a traditional top down fighter plane game, with great touch controls.. Great graphics, good sound. Sky Force has actually been around for a while, but they do a great job of updating it. Simple play, reminds me of one of my old favorites, Raiden. Good upgrade path, it get’s really hard about halfway through. Fun, addicting, well worth your time.
