In fact, the levels that I can't open on NLEditor are the levels where I have grouped parts together (using the Group button). Apparently, NLEditor does not recognize these kinds of objects. Is there a solution to fix this problem ?

Proxima : Thank you for these explanations ! I totally agree with you. Regarding the traps, indeed, the holes should be part of the trap's graphics. I'm sure you can do something awesome !
(since I love astronomy, I like your nickname very much... and your profile picture !)
Ericderkivots : Yeah, I've thought about it too, but, I admit, I don't know what music to use ! If you have ideas for me, I am (very) interested ...
