Once I got through the menu it was less laggy so that's good! I like the idea of navigating by leaning and stepping forward on the broom. I couldn't quite figure out killing the dragon, but maybe in the polished version with sounds I would be better at it. Perhaps some visual cues for when the player hits the enemy? Anyways, nice work here.
If you have a second to check my game out and drop feedback/a rating, I'd really appreciate it! https://itch.io/jam/vr-super-jam/rate/1249489
