You sure can! We're pretty relaxed when it comes to YouTube and Streaming (Twitch, etc.) permissions. We only ask that any content includes clear information that Don't Starve: Shipwrecked is in currently in Early Access, is constantly being updated, and not yet a complete game. It would also be super cool if things linked to http://store.steampowered.com/app/393010/
, but it's not mandatory.
