We are back from holiday with some great news:
First of all, we would like to say thank you to Ricardo Benton, he sent us a Brazilian-Portugues language pack.
Currently the whole codebase is being reworked. We gone for an object oriented approach, and separated the code into packages about the logic and graphics. All code implementing game logic will be unit tested along the way. We also introduced a new, more modern game engine, which supports all major platforms: Linux, Windows, Mac OS-X, Android and iOS.
