Holy hell, thanks a lot!
I love board games too, I really wanted to recreate the feeling of real piece and movements.
At first, it was designed as a two-players game, but it got changed since I figured testers would be playing solo. But I intend to add the two-players local after the Jam ; the code is already there for it, it just needs a bit more work ^^
Honestly, the dots are just a holdover from the time when the game was just plain without animations for maximum functionality and ease of debugging: I just needed any visual indicator to be sure my pieces behaved correctly, and it stuck when I started working on the design since it worked pretty well! =D
