"I've just reprogrammed a dog to attack mushrooms," is how Sam's preview (opens in new tab) of The Magic Circle begins. Y'see, you can focus on the story's clever game-within-a-game meta-setting, or a development team that includes Irrational alumni Jordan Thomas and Stephen Alexander, but sometimes it's best to focus on the important stuff. Programmable dogs attacking mushrooms.
The Magic Circle is in Early Access now. As hinted above, it's a first-person puzzley-adventure thing set inside an unfinished fantasy game. You can edit the game's creatures—swapping behaviour patterns and even body parts—leading to a multitude of solutions to each objective.
The team are hoping for a "relatively short" six-week Early Access period. For the most part, they're looking for feedback on localisation, and to officially recognise certain player-found solutions that will inevitably be created. As always in a systems playground, it's hard to support solutions that the developer hasn't conceived of.
Additional language subtitles aside, the Early Access build is "feature complete" and contains the full story. I can't confirm if that story includes a chapter where the game is released on Early Access.
