Thank you for trying it out! Yes, as it's currently only 0.1.0 you can imagine the future is full of more content and features!
My current update is going to include the ability to battle and take over castles and battle beasts. So you will be able to quest in the worlds you build. I also want to include some other elements like villages, methods of transportation, and eventually stores/markets. Can't really commit to a timeline at the moment, but I'm completely open to suggestions!
