First of all: I had no problem signing up or logging in. However, I noticed right away that there are issues with the german localization, see the example in the screenshot, it's the 2nd text field to pop up and I am considering to switch to english because I am sure that version is written much better! :) :s
If you wanted to fix this particular one: jemandem instead of jemanden (Dativ) and Handybildschirm as one word. Ignoring the sentence structure here. Not going to deep into it, because there is something here and there and this would become a long error-report. A short note to punctuation: the word 'indem' generally needs a comma (, indem). Do you eventually have a community sheet up for translations? The gameplay is good and I think some proofreading would not hurt the game!
I am an hour in but I will update this in case I run into bugs! I like the concept of the free MMO, especially playable in browser. I got great hopes for this to evolve into something massive!
