Dear adventurers,
We are happy to inform you that you can now play online COOP with your friends from Nintendo Switch WORLDWIDE. There is no need to be on the same device anymore - choose your region on both Nintendo and PC (or any other console) and play together in an online session.

We will continue adding improvements to the game.
See you bipedal!
