Week 9 Prac B

grid system looks like

Here is my plan:

However, i will need a lot of things to change in my code. For my last prototype, i used mouse to move and point to the targeted square and click on it. But this time, i have to use keyboard keys to press on the targeted square. So i have to change basically more than half of my code.
