Whoa there, keep your pants on. We will be sending out alpha copies to appropriate backer tiers very shortly after Kickstarter completion, if not immediately afterwards. Release copies will most likely be sent out via Steam/GoG/IndieGameStand keys.
Long Answer: Our focus is making a game about spell-casting that feels ridiculously powerful. We don’t want to be restricted in the design of our game by ruling out spells and abilities that would be overpowered in multiplayer, so for now, we are only focusing on a single-player experience.
