This is how it looks on my end. Currently I'm using chrome to play in windows 10. Maybe this is related to the game playing in a browser, some functions of the engine might mess up with html5. My godot game worked properly on desktop but crashed in the browser every time it called a function to get a random float number. A quick workaround fixed it. Maybe you have a function that is not browser friendly for some bizarre reason.
Another note I forgot to mention earlier was that the character clipped through the floor when she was below an elevator while it was decending, but I remember you posting about it on an /agdg/ thread.
