A new update is available, although with some delay. Among some bugfixes, it also introduces a new feature: Doors. Of course you can interact with the doors, they're admirably suited for opening or closing.
The update will be automatically applied when starting the launcher.
The changelog is available here: Forum.concept-game.net
Here are some screenshots:
Doors. Love em. Is that top one modeled off my front door?
Hehe, who knows? ;)
