Although the canvas can be rendered and I can see three rabbits in browser,it's hardly to move the mouse to update next frame. Everything just like be stopped even couldn't open the chrome devtool...

Hi, thanks for the feedback. Responsiveness on lower end systems will be bad until i get around to implementing tiled rendering. Right now the renderer tries to perform one sample for all pixels in the canvas every time the requestAnimationFrame callback gets called. In the future it'll dynamically render as much of the canvas as possible that'll still keep the UI running at 60fps. In the mean time you could lower the resolution with the res url param.
