I agree with both GP's comments. I think the path is confusing because it's shown like this:

A>>>>

and when the opponent makes another move:

BA>>>>

So the arrows say "this is moving forward in time", and point to the right (which is usually where you add things). But then the new moves are added on the left, behind the arrows.

Consider clicking a tile twice to confirm move. Or once

Twice seems smart. Too risky for a single click

yea

- click nearby tile should move - click distant tile should pounce
