We have recently put together a road map for Rubikingdom's early access content. While we are planning on a late spring release in 2021, this may change as new content is added. We invite you on this journey with us. So join us on trello and let us know of any feedback or ideas you may have.
Thanks in advance,
Sthealz and Nox of For/War Games
