Actually I'm still getting German names for units, buildings, workers, etc.
There is only a button of advanced translation (under Misc options), and it requires "Transifex" user name and password.
Its obvious that you have a good programing ability and art sense. I have few ideas if would like to add to your nice design;
1- Adding another abilities to the sorcerer of hiding things (workers, troops, buildings, etc.) and make them invisible, to avoid enemy attacks (or make better surprising attacks),
2- The ability of the sorcerer of shielding troops (totally or partially) during battles,
3- The sorcerer’s ability to change resources type (change stone to gold).
