Hello.

The game barely has multi-lingual support apparently:
- Only minor UI elements are translated, most notably the in-game time;
- Changing $LANG to other languages does not fix the problem, the game remains largely untranslated;
- The French and Czech translations, available at the web site of the project hosted by Source Forge, are missing from the package.

As a result, the game is only available in English.
Many people expect to play the game in various languages that are described as supported, however they do not seem to be.

Have a good day.
