Warfare & Havoc - Our first Android game [released] Thread

We have just released Warfare & Havoc, a war game for Android and also our first game.
It is a real-time tactical war game that contains 27 levels of which the first seven are free. 
 
The game was developed by two Estonian IT students as a hobby project. 
We have worked on this game on and off for two years and finally it is finished .
The game is built using the libgdx framework.

We would be thankful if anyone would review it or give feedback or point out what should be changed/added.

The game can be found in Google Play:
play.google.com/store/apps/details?id=com.bavuwe.wah

To get the unlocked version:

1. Download it from Google Play
2. Navigate to About screen (click the "i" button)
3. Press Android Menu button and enter the promo code "oviroei" (without quotes)
4. Enjoy the free release!
