Hmm, I bet the problem is my code expects touch events instead of mouse events when a touchscreen is present. Unfortunately I don't have a computer with both touchscreen and mouse here to test with so I didn't test that case. I did implement both gamepad and touch controls, so you could try them to see if they work.
