I haven’t listened through the episode, so maybe this is resolved, but I had to pause and post that as soon as Brendan started talking about those wibbly hands, I knew the game he meant was Hylics by Mason Lindroth.
I definitely recommend playing the first one. Mechanically it’s a very RPG maker game, but visually and tonally it’s completely its own thing, and doesn’t overstay its welcome.
The sequel was a little disappointing to me. I remember it being a little more narratively straightforward, and otherwise was more of the same, and the inclusion of 3D spaces didn’t add much to it. So if you just play the first one, you’ll get the idea.
