Edit: Seems it's mobile only, or the mouse drag event handling is masking the click event. That is, it rotates for me on mobile, but not on my desktop browser (chrome 58.0.3029.110).
Issue is here: https://github.com/stared/quantum-game/issues/5 - as it seems that more people have the same problem. Any pointers how to solve it (or Pull Requests!) are welcomed! :)
