Played on Valve Index. This feels like a great concept.
Some issues that may be related to Index were:
1. The first, very minor, is the player's hands were at the "wrong angle." Throwing quotes around that because it's probably because of the angle that the Index controllers report vs other controllers. I have seen a lot of other games with this and it makes me think there should be a way for SteamVR (or you) to detect and correct this. Probably not something you can test without Valve Knuckles of your own.
2. The player model's arms aren't as long as mine are, and so grabbing objects was more difficult than maybe intended. I have seen other games put the character hands exactly where the controllers are, warping the model as needed.
3. The player model got stuck a lot, and the torso didn't follow my movements. I thought at first this was a tracking issue on my end, but I could 'control stick walk' to translate across the map and the model didn't follow. This happened most often when near objects in the map, or when holding objects.
