Hey, as Afonso, said, the webgl version surely introduced some latency (partially due to how things were implemented, so you can say it was a bug)
As I think it can be considered as a game breaking bug for the webgl version, in accordance to Brackeys Jam Rules, I just updated the game so that it was less of a problem
All the timings of the tracks are still the same and have not been changed (as it wouldn't be a bug)
Thanks again for the stream & feedback!
