You should probably make an WIndows build because it lags extremly for me in WebGL - I don't have a great computer, but its unreasonably laggy even for my computer. (AMD Ryzen 3 3200G and GTX 1050 TI)
Sorry about that! I'd assumed that because it could run fine on my old 2015 macbook that it would be able to run on all systems' browsers. Guess there's always going to be something I'll never know to expect, though.
I uploaded some downloadable builds for whoever prefers those over in-browser. Hope that helps!
