Hey,
I can’t verify this on all devices therefore I do not know if it is to do with the device or the engine. When running my game on the Nokia Lumia 820 which is my test device I’ve noticed that pressing the screen a number of times causes Input.touchCount to get stuck at a certain value and never go back to zero.
I have verified this with a sample project and with the latest marketplace version of Temple Run. The sample project is attached. Is there a solution for this. My bug tester will NOT let me go gold with this present.
