I've started doing some bits and pieces on Vertex Dispenser again, after having done nothing on it for several months. I'm going to finish it, dammit! I've actually fixed some of the problems in the network code, which is awesome (but it still crashes sometimes, more to do there) and I've done some work on the campaign - mostly trying to get the difficulty right, but in the process I've also made some of the level designs a bit weirder and scattered more shiny particle effects around:
I think it's an improvement. Possibly I have just gone mad.
