Here you download the latest version of the game. It only works for pc at the moment.
The file is a .rar file which you unrar with winrar
In game folder there is an updater: Updater.exe. Run it to update to latest version.
When you play the game you see your version and latest released version in left bottom corner
When running Updater.exe have patience! It might look as it froze but it doesnt. It should take 1-15min with fast internet.
