Now that the level editor has arrived here, I'd be thankful for any hints and would like to make a list.

I'm considering buying this game mostly because of the editor, to enjoy community generated content, therefore it's very important for me to have the assurance that other people's created levels are available in the GOG version. Please, GOG staff, I kindly request an answer: can other people's levels be seen/downloaded/played in this version? Thank you.
