I'm glad you liked it and played it until level 27 :DYes, there seem to be a bug there. "BIG" is twice on the board. If you picked the one to the right of LANGWEILT then VORBEIGING would be solvable. Thank you for letting me know. I will fix!
Nice, I did the workaround and solved it without any other bug. Guess I have to do the English version next :D
Thanks for sharing!
Awesome :)
