It's now possible to play with a friend via local network in cooperation mode. There are still some limitations (like lack of in-game chat) I'm working on. However you can enjoy all singleplayer features in a multiplayer game.
Apart from multiplayer update, new version of the game has received graphical boost. A lot of items and monsters has been improved.
Some images are still placeholders, but it'll be progressively changing in feature updates.
