Co-op?

[Mattressi]

Just wondering if there's any plans to patch in co-op or if there'll be a second game or expansion which contains co-op. I think I'd really enjoy this game, but I tend to only buy games that my wife and I can play together.

Still, I'll likely buy it since it's so cheap. But if there's a future patch or release with co-op I'd happily re-buy it for my wife at the normal price.
