the process of the interactive story

Currently, I have finished most of the PS parts, including around 40 pngs and the post. 

The technical problem I am struggling with right now is how to create new elements such as “buttons” in the function and put them into use. The way I am dealing with it right now is to create all the buttons in advance and hide them first and then let them show up in the function. But I think it’s not the best way.
