Hey there!
From what I could find in other forums and the likes, there sadly seems to be no crossplay.
I'll keep my fingers crossed that it'll come at some point in the future, as I'm in general a big fan of cross-play, but so far I don't see any plans from the developer to introduce it.
Hoping the best for us all, and that you still find ways to have fun!
Greetings,
Bryan
