Wonderking Germany is appearently making an English version for non German speaking people
Dear European players,
welcome to the European Version of Wonderking. We have had several questions about an English Version of the game, and here is your answer:
We will be releasing an English Client within the next 2 months and are working hard to deliver it as soon as possible.
We understand your eagerness and we are sorry for the inconvenience caused.
Your Wonderking Team

At least it's better then not having an English version but still, it's 2 months for others
