thanks! i'll try if i find time, but it will probably be a good while before i can update the game and it might be hard to find a fix if i don't have a good way to test the problem myself.
just as a side note, wireless headphones will introduce input latency if you happen to be using them, and there is a input delay callibration feature in the options menu if you want to see if that helps you in the browser version. not much i can do about the stutters though, it's just how WebGL works in browser...
