On line check for a maze

How can I make an on-line check for such a maze



You could pin the problems to a graph page. You would need a point for each problem and a draggable point for each answer. You could use the CL to check criteria, maybe if the answer is dragged within a radius of the matching expression. I’ve included just the beginning of the idea here:

I think there may be a way using xValuesAt and/or yValuesAt. See the Types section, subheading sketch.
