Cool, liked the quit button mechanism, though I accidentally triggered it the first time. Nice set dressing as well. Gameplay concept definitely can work too, with more.. time, of course.
I am personally fine with smooth movement; though thinking about how it's kind of hard to build a little settings menu just to support different movement/turning styles, feels like it'd be nice to have some global way for OpenXR users to specify their locomotion preferences to games. Sort of like the 'prefer-color-scheme' dark/light in web browsers.
