Cool game concept! Jumping in VR with a button was pretty rough on the stomach though. Also, interesting enough my frame rate had a lot of spikes in it, I'm not sure what was causing it to constantly spike up and down. However, after dying a couple of times, the frame rate finally settled down and became consistent - something to look into if you continue development is all.
I would also recommend slowing down the wall that kills, or maybe allowing power up pick ups that pause it completely for a short period of time. Stuff to think about is all!
Good physical game!
