You can play the demo right, now before the project gets shut down.
Developer WinterDrake is looking for more people to help make the game a reality, and even has a contingency plan for when Nintendo inevitably tells them to knock it off.
“If Nintendo asks me to stop using their IP, I do plan to continue development with my own original characters,” they told Kotaku.
“I’m having way too much fun creating this world to just give up.”
Essentially the game is a 2D Breath of the Wild, with interactive environments, smooth animations, a physics engine, day/night cycles, and even crafting.
If you want to try the demo, you can download it now for free.
