It took longer than I hoped, partly due to real life events, but the multiplayer beta is now feature complete! That means you can complete all the current single player quests with friends, build and ride vehicles, and test out all the features.
If you haven't heard about the multiplayer beta, or want to know how to access it, check out this news post:

There are currently no known bugs or issues with the multiplayer beta, although I've only tested it two player with a fellow dev. If you find any bugs, definitely report it! Assuming there are no major bugs, I plan to push this build to the default branch in about a week, so everyone can try it out. I'll keep the beta branch available so you can access your beta saves (as the beta has a different saves list than default), but once multiplayer goes live, the beta branch will not be kept up to date.
As for what's next, I have a growing list of minor improvements and quality of life changes that I've been putting off while I finished multiplayer, so the next update will probably be a quality of life one. But after that, I think I'm going to start the magic path! I've already gotten a lot of models done for it, like the baby dragon below:
I hope you enjoy multiplayer, and are looking forward to the next updates!
