Making a tutorial is impossible for 6 Nimmt! now. I'm not sure why, but when you try to make a comment the second or third time, you get this red warning: "Bad argument type: move should be a Number (positive integer) (NaN)".
I would have reported this on the bugs forum, but that forum is a nightmare to navigate now.
