I haven't looked at keybase in while, sigh.
I don't currently have the right stick hooked up to anything.
When you're browsing, stick/dpad/arrow-key movement is purely geometrical -- it ignores path directions. I figure that people will just hold the stick down.
(When you're playing, purely geometric stick movement always works. But moving in the path direction should *also* work, even if there's a bendy path. Making all that work was fun.)
