Chess game updates

I recently got my first ship rated and I understood what mistakes I made and what I needed to fix. I understood that even though the game was well made in terms of how it works, it wasn’t user friendly and the theme made it harder to see. Thanks to all who helped give feedback for this, and my first change is to make the pieces actual vectors. This was an issue all of the users pointed out, so I hope this fixes at least one of the problems. I will continue moving forward with this in mind, and I am currently working on my other changes as well. (This is the only one that properly is working so I wrote about it)
