Great game! I saw this at the Austin VR Game Jam and was probably one of the most creative use of VR experiences there that I saw. Definitely hook it up to Steam Leaderboards and also it seems like it's building off of Pac-Man with the little fruit items, the return symbol, and the whole moving around to avoid the "ghost" dragons. Definitely build more on top of that, make the return symbol allow you to punch the dragons to destroy them and then they respawn and maybe as game goes on more dragons spawn or this allows you to go for level based structure. Good luck with the progress!
