Played with only the Leap and loved it, I can only imagine how good it must be with the Oculus as well. In the spherical mass scene, I really liked the effects of removing my hand and then replacing it on the other side of the tracking range. The spotlight hand scene is my favourite though, being able to control the size of the light by opening and closing my hands felt fantastic! Very polished! The shadows cast under the title from my hands were a really nice touch.
The beginning bothered me a little having to remove my hands from the tracking range to click the right arrow, but it was understandable considering that is also your scene switch control.
Would be really cool to be able to have some (even small) effect on the music playing.
Had a lot of fun with this, well done!
