Haven't worked on it since its demo release. I've been fooling around with the Hammer editor from Valve.
I got the orange box and I have been playing around with their half life 2/portal/team fortress 2 editor.
It's quite an editor, hard to get the hang of, but I think I may have started to get the hang of it. Not going to be able to mess with it for a while soon. I have to get back on track with mario doom.
Not to mention a possible idea for another mod in the future ;)
