I'm not sure if they really need to add more to it, content-wise. It's a pretty complete game from that standpoint.

Maybe more monsters with different abilities to fight would be neat?

Multiplayer support would be the biggest thing that's missing I think.

That was my understanding as well, but that they had also released the source code so others could continue if they wanted?

I've been loving this mod for the last few weeks. What was the technical challenge keeping it from being playable in multiplayer?

Maybe we could recruit a few devs to keep up the work?
