As we're close to releasing from Early Access we've raised the price back up to $5.99. Those who have claimed the game when it was free, you will still be able to enjoy the game as normal. Moving forward we want to do a large update in the future, bringing it closer to our original vision of the game that we had back in 2014. What we want to add in are Adventure mode, NPCs, Quests, Rune Pets, Crafting, and more. When these larger updates come out the price of the game will slowly raise as well. Thank you for your continued support.
