I run a "Lemmini Extras" Group on Facebook for people who use Lemmini or SuperLemmini:
https://www.facebook.com/groups/lemminiextrasTo start off, this my first levelpack, compatible with SuperLemmini only:
Prince Jamie's Super Challenge Pack Set 1:
This pack includes 15 challenging levels using the Tilesets from the Original and Oh No! Lemmings with a new object: The one way walls, based of "Super Mario Maker".
But in every Set, there will be 1 Special Level, based of some video games you may or may not have heard of, this one includes "The Legend of Valkyrie" from Namco.
