How do exact instructions guide a character?
Instructions tell the character where to move. Each card has one exact meaning. Right means one square toward the right side of the page. Up means one square toward the top.

The character starts in the bottom-left square. The cards say Right, Right, Up. Two right moves bring it to the bottom-right square. The up move then brings it to the star.
The cards are followed in order. They do not ask the character to guess what someone wanted. In this picture, the cards move it one square at a time; they do not turn it.
