TrackStrap™ and Vive Tracker features:
I realized that instead of only having specific beatmaps with orbs for the feet (which we eventually will have), or pushing more or less random orbs from osu! beatmaps to the feet, we can simply move the target area down a bit and play any osu! beatmap with hands, head ... and now feet.
From the Steam Page:
Get your workout with any osu!-beatmap in pure rhythm game environments, or immerse yourself - guided by dragons - in the mindset that will save our lovely little planet ... in the only room-scale Virtual Reality rhythm game that precisely knows each note of every song in the game!
