Jazz Jackrabbit 2 Online

Fixed Now ! You can play the lvl with the full files

Your screenshots show that the level uses a custom weapon, but you don't include the script file to make that work. If you're using MLLE, try the "Tools -> Package in ZIP file" dropdown menu option: that will give you all the right files so that other people can play your level.

That said, we can basically play the level, since there's not enough here for the secondary weapon to really matter. The initial section is a bit interesting because you have to jump onto the sides of the pillars, then from the sides onto the tops, dodging (or stomping) the skeletons. But everything is buggy. Destruct scenery doesn't really work (https://www.ninjadodo.net/htjcs/ht/anim.html), hooks don't have the Hook event, the sky doesn't tile correctly because you didn't resize the background layer. It's good that you have different challenges, that part of the layout is interesting, but the basic technical details aren't here. Read some tutorials, study some other levels that do the things you want to know how to do, find a friend who can verify that you actually included the right files to play your level.

I forget script files !

Your screenshots show that the level uses custom weapons, but you don't include any of the script files to make that work. If you're using MLLE, try the "Tools -> Package in ZIP file" dropdown menu option: that will give you all the right files so that other people can play your level.

In description it says Battle, but you labeled it as 'Single Player'. Maybe edit the upload?
