So what Dialogic does is it creates an 'input catcher' as a part of the scene, that means that you can't click anything. You can turn off the input catcher layer entirely through Dialogic by making a new Style, or you can shrink the input catcher by editing the scene. But if you need something on top of Dialogic, then you can always put it in a canvas layer and have that above Dialgoic which is at default layer 3.
Thanks! I'll check out your game when I have time!
