Hi, sorry I dropped the thread on this. For what it's worth the game does work on my Android phone. I have to wait to test it on my wife's iPhone to see if that's the issue. It is the case that not all of the event handlers map cleanly to mobile devices. For example the notion of a mouse move doesn't really exist for mobile there's only drag, also arrow keys on the keyboard are usually map to swiping on a mobile device. And we don't have any of that implemented yet
Anyway all of this to say that there might be a way to get around this for an iPhone by writing a little bit of extra code. I have an idea but I might not be right, but if you want to try it before I have a chance to get back to this go ahead. The idea is to sort of invent your owned click Handler by using mousedown or mouseup, or even both in combination. I'll have to wait to test it on my wife's phone. But I'll try and see if it works and get back to you.
