Ah yes, probably needs a bit more explanation there, I wanted to expand that tool with various features like tracking user performance for each case and repeating cases with a low-performance as well, but eventually moved on from the project.

I perceive this kind of stuff to be a bit lacking in e.g., Duolingo which is more focussed on phrases (and I found it to be a bit too repetitive with phrases you already know, while not being repetitive enough with things you are struggling with) which is what motivated the project in the first place.

That particular example I intended the genitive case, so "das Essen der Frau" meaning the woman's food - but definitely need to make that more clear!

Thanks for the feedback!
