I had sent my levels and worldmap in this forum on 23 Jul 2015. It had been packaged as an add-on named "The Frozen Continent", and added to Contrib Levels.
Since that, I have added 11 new levels and I have enhanced the 11 first levels :-)
I have also modified the name of the world: from now on it's "The Frozen Mountains".
I send all the new files in attachment.
Could you add them as a new add-on named "The Frozen Mountains"?
And maybe delete the old one named "The Frozen Continents"?
