Chapter: Commands

The tasks in this chapter were no problem for my daughter. I think that other children of a similar age also understand very quickly how things work. In the end, it even turned out that she didn’t find the long sequences of commands very exciting see task #7.

On the other hand, I have to say that I personally found this approach to be a good one. I think when you realize yourself that you could optimize things, it’s time to learn new techniques.

Also, in each lesson, the newbie first gets to know the environment. Besides collecting gems, tasks like toggling switches or using a teleporter also come into play.
