Our Game is now finally available at Amazon for players that have an Amazon Fire Phone or Tablet with gyroscope or for people that doesn't have a PlayStore installed.

This is the same Version like in Google Play because we didn't use any Google Services in our App - It's Android native with LibGDX. That's why we can provide the same App without Google ;-).
Feel free to be the first that rates our App at Amazon :-)
