Incredebly impressive that you made a VR game. Respect for that.
I had a problem, that I didn't get any sound but that's most likely due to my dodgy Virtual Desktop setup. Other than that (and the bugs you described on your game page) it worked fine.
What should I say, it lacks polish. The particles look a little weird, the controls aren't perfect and the game is a bit tough to play.
I think what I missed the most was intstructions within the game. What are the controls, what is your goal and how does the game work.
But I'm thoroughly impressed what you did manage to do. Great job!
