Spooky! And I love the title. my only suggestion is its sometimes hard to know if the text is done or not before you press the button, I accidentally missed some dialogue at first because of that.
I agree with you. The original plan was to make the button to show up at the end of dialog, but I couldn't figure out how to code that in time. I did move the button to the bottom of the text to try and make it more obvious when the text was done, but it's still more confusing than it should be.
