Thank you for the feedback! ( •̀ ω •́ )
I'm not sure what could be causing the lag in the browser build because it seems to work fine for the most part on my machine. It also seems to work fine on the windows build. It could maybe be because of unity's ai nav system not being tied to the framerate correctly but I'm not sure (this is my first time using unity's nav mesh system). This is also my first ever time making a web build so stuff like this is hard for me to debug correctly because I know little to nothing about web ports.
Currently I'm not sure if I will update the game but ill keep this in mind for the next time I make a browser build. U_U
