I used to play this all the time with my sister. Does it have online multiplayer?
Some clarification from the devs...
"Today we wanted to do a better job of communicating our plans for co-op. We mentioned in our rewards that online multiplayer would be contingent on our platform partners at release time. We meant to say that we wouldn't be building and maintaining our own game server for matches, but we do intend on bringing local co-op as well as peer-to-peer network co-op into the game, so that one friend can host others in an online game."
So, yeah. Looks like it. The co-op plans were a bit vague initially, but I guess they just weren't sure whether they would be hosting official servers or not.
