Amazing game, the music and fast paced action made me do a few runs.
It was a bit hard at first, until I understood I could litterally empty the shelf besides me and throw book two at a time, really felt good!
I ran into a little bug (not being able to throw the right book if I had picked one on the other hand, maybe it has something to do with still holding the other grab button?) but nothing that hinder the fun.
Great job!
Tested on occulus rift and 1060 3go.
