Hello folks.
I got new plugin that helps with Steam SDK so there is a lot of interesting features could be added in future, but right now you can go wishlist game by clicking on button menu and the game page will open in steam overlay. So, you also can invite friend or connect to friend using Steam Overlay buttons.
By the way, there is option to connect to the session by its name, isn't that a joy.
More than that, it is possible to join random session with some strangers, and to prevent your session from strangers, you could private it.
Stay tuned and wishlist game if you didn't already. Game will not participate on summer game fest but I guess there will be demo somewhere near that.
Have a nice life,
