I am very happy to help, but the matter is a bit complicated, because I named everything in Hungarian during the preparation and the explanatory texts are also in Hungarian, because it is only info for me. :) That's why it would be difficult to learn from this. But what I can do is write an email to info@wls.hu and I'll send you material from it, and maybe I'll try to rename it so it's understandable. And it made with GB Studio 2.0 !!
