How do I…

When previewing my mobile game Roo-Dee, touch works as expected on PC, iPhone, and other mobile devices. However, once published to, a single touch on iPhone devices sometimes registers as two touches instead of one. I have linked to the game on below.

What is the expected result

A single touch/tap on iPhone should rotate a wire 90 degrees during gameplay.

What is the actual result

A single touch/tap on iPhone sometimes rotates the wire 90 degrees, but sometimes 180 degrees.
