Thank you! Unfortunaly the stutter is native to WebGL... But what browser are you using? We are investigating issues with Firefox and Edge mainly. Edge works after reloading apparently. Did it freeze for you?
I was using Firefox, I think the game froze a few times before new dialogue appeared or when the camera was turned to a new area that wasn't rendered before, and I got stuck permanently the first time I saw the shadow presence.
I see. Yeah Firefox is the worst performing one. Regarding the stutters, yeah it's a shame; that's the shaders compiling the lights. Very tricky to pull off, especially in webgl. A small price to pay to get a prettier game though. Fortunately once they load the experience becomes smoother.
