Hmm, I think you should talk with Exl about how much of that would actually be possible (I guess most of it would be, except for that glowing stuff
). Would mean a lot of new tiles and that you can't *cough* get inspired by the original levels. Sounds like a nice project, but not so sure you can do that all on your own. Why not make one 'normal' level first, just to see how the editor works?
