Hello community, from what i know and what i obviously realized is that the story mode is incomplete and it would be about time we did the last few islands to complete the story mode, but thanks to its level editor it will be the easiest task (but we must add the corresponding roles and music).
As I see in your wiki and in some files of your source code, the next island is Tropical Paradise, which is already visible concept in the plugins.
The reason for this new theme is to see if there are more concepts for the other levels as I think it should be seven islands in total just like in the Super Mario Bros video games.
