One thing that I developed for the "charting the course minigame" is the drawing mechanic and custom cursor. The drawing mechanic uses the line render component to draw out a line ONLY IF you start at the correct start point and if your mouse is down. If you lift your mouse up again and click again the minigame will reset. As for the custom cursor, you would think we used the unity cursor setting but that's not true. The reason I'm not is that the unity cursor is always set to a specific size. So instead we are hiding the base cursor and just using a custom game object so I can set the size and offset. 

Overall this tool has further deepened my understanding of what a tool could be and how to do something that, while niche, is extremely useful when needed.
