Just found this topic (again) and am totally excited about this announcement!
I would be interested in a better and easier level editor - I made several levels for Jumpan UC (the very best Jumpman remake ever since done but unfortunately abandoned in a very useable beta stage - the author is known for never finishing his creations). I also have a collection of Jumpman UC games never released. There was one specific by a fan that is so extremely professional that it could have been sold as a new game back in the days: Collection Of Torture. Well designed level, even with new elements and new effects. If you would like to check this out I can share it.
