Thank you so much for sharing your first impressions! And you did nicer music than me with it :) It is so useful for me, as I didn't do playtests with friends/family
What controllers are you using? Pico
I modified the rumble script from the xr-tools-demo to allow very low magnitude rumble, and very short duration, which works perfectly with Index controllers. But maybe it's too low and get filtered out by other VR devices/API :/
I made a new build, with higher rumble magnitude and duration of 50ms instead of 1, hopefully it works with every type of controller this time!
