Turns out I’m learning a lot about how web builds work as people comment about control troubles but I think I’ve figured it out. My guess is you hit enter, or space to start the game since that button is highlighted, (so it works with gamepad) but you actually need to click with the mouse so the game has focus and can properly capture the mouse, which happens when the level starts. I clearly have some infrastructure code I need to work on to manage this. Regardless, thanks for giving it a try and letting me know about the issues.
