Risp: Ahh i see, noted.

A beta of the Jazz level editor is now uploaded, run those updaters people !

There are no Help files yet, the first tip to get you started is that you hold down shift and use the mouse and mousebuttons to move around...Ive tried to make the interface reasonably simple...it takes a little time to get use to though.
Also when plaing objects make use of the mouse wheel .... i'll send out a decent help file soon across the updater.
