Dungeonhaven is a PC and Console game being developed by just two people working in their spare time. Planned release is in 2019.
“Players take the sword of a knight resurrected from stone, called into the world as a pawn in a war between living dungeons formed from the twisted souls of those trapped within their walls. Manage powers gained from defeating bosses in fast-paced, deterministic combat. Players start with the ability to turn to stone at any moment, even mid attack animation, and will balance other risk/reward powers as they gain them.”
