Yeah, it's not a "German 101" course. But thanks for the feedback, it means to me I need to be much more clear what I want. That my target audience is people who are already learning german and want some additional help aside from their books or lessons.
I also would like to make the relations between the words more graphical, I just didn't have the time and I haven't found the proper tool yet to visualize it the way I would like to have it.
