Yes, an extension is this week's game of the week! We know about the technical difficulties of this week's GOTW, and we're looking into it. Hopefully you can all vote now. Congratulations to Andos on winning this one! And sorry about the GOTW image - I no longer have Photoshop.
Yes, this extension is definitely mostly a graphical enhancement. I don't know how collisions should work in this object since it could probably confuse people more than it would help. Like are you only supposed to collide with the part of the object that has a line length longer than the z-length? Or the whole object?
