February 12 - 19, Steam will host Steam Remote Play Together Fest, featuring games with the Remote Play Together available.
AIdventure is one of them! Yes, you can now write stories with your friends on the internet! Only the host has to own a copy of the game!
I remind you, by buying your game on Itch you also get a Steam key of AIdventure! To use the Remote Play Together feature you need to run the game on Steam.
Enjoy ;).
