Just wanted to follow up after a little more investigation into the issue. I have added a kluge to work around the focus issue on web. If you click on the game once, it should enable keyboard controls. Let me know if it works now!

Without seen the code i would say that the touch screen system might be overlapping the keyboard controls?
