What kind of multiplayer are we looking at here? Online or no? Seems like a no brainier to me; so many things with this that seem kind of like a lost opportunity.
Haven't played but there is absolutely nothing MULTIPLAYER about this. Check the app description again. I think it's just a level download. Also there is a paper dungeons lite if you haven't tried it. Not that there should be at this price.
I really like this game. It's a good game with a ton of content and different play modes, but it could be a great game with a little more attention from the devs. It has quite a few bugs (minor but annoying) and the comments by previous posters make a lot of sense. I hope the devs are just quiet and busily working on updates.
