Is Shared Screen local coop planned for early access, or is this going to be added prior to launch?

This wonderful game on sale now. My friends bought it yesterday, but not me or them can create a game session. Just wanted to play in full party of 4 players, but... Multiplayer still working?

I don't see either called out on the official store page but buried in the update history v1.05 seems to have added controller support and per ProtonDB the game reportedly works on the Steam Deck. Does anyone have input into either of the above? And just a note to the Devs, if controller support is indeed built in now and this does work on Steam Deck, you may want to update your listing as this appears to be a great game for handheld play. Could open up an entirely new audience of potential buyers if ...

Im playing offline as the wolf guy atm. only 20mins in but its really fun. I would like to play online but my internet is trash atm.

My bro and I need 2 more players for the achievement.
