do you have any feedback? What would you like to see next: I plan on much more development based on feedback
The overall UI you provided is really solid! Lots of settings and things to play with. You sectioned them rather nicely.
If you want to make it even easier for a single player to learn, you can even implement a tutorial that shows how a pawn can be captured. I know there are tons of visual learners and a little indicator may help them comprehend the project furthermore :)
Overall, the project is really well done, and I commend you for your brilliant efforts!
