It happens to all level/packs, with or without j2e files. :/

But really, what can I do to make a 2D game different from the original game? The only way I can think of is to use new tilesets or create new type of puzzles. Which can be hard due to the lack of possibilities in JCS, for example, I´d like to be able to make moving tiles and you can control their moving path. Something that can open up bunch of new possibilites, and not to forget extra layers etc.

I wish Epic would release new patch that creates the glory of 2004/2005 for JJ2.
