Sorry, for some reason the game is really twitchy and only became like this after I made it a web GL.
idk if it's the issue, but if you use cinemachine, it auto puts the update mode of the camera to a normal update, if you have functions that do fixed updates in your scripts for character movement and camera controls, it can cause twitchyness, to fix this set the update mode of the virtual camera and/or cinemachine brain to fixed update, idk if this is the issue but it might be so here you go
