This game would be excellent to play on google cardboard VR, especially given the 1-button limitation that cardboard currently has. Players could aim with head movement, use and release the button to move, and propelling yourself through the air in first person would be even better in VR. You've proven that this concept on its own is fun enough just in the prototype, and have done it in a style that could easily be rendered on a mobile device. Anyway, should consider it!
