Years ago I saw a guy do a video on his voxel based space game and I have never seen anything of it since - eviltoast

I have tried pretty hard to find it again to no avail, it was just some guy in his house talking about his game and showing clips of gameplay, and I feel like his wife was in it too? The gameplay involved you cruising through space in your spaceship, exiting the cockpit and walking around while in transit, even going out on excursions - all in first person. Does anyone have any idea what I’m talking about?
