TrackStrap™ and Vive Tracker features: 

The gameplay of the full-body version is different than the regular version. In the full-body version you get to use both of your hands and feet to kick and hit stuff. In the regular version of Tornuffalo, you only use one hand.

From the Steam Page: 

Humankind has faced earthquakes, volcanoes, floods and hurricanes—but the most dangerous natural disaster is a weather phenomenon known as the "Tornuffalo." Get ready to dodge, block and hit in this room-scale VR game.
