It IS glitchy. I DIDN'T MAKE IT DETECT SITUATIONS IN WHICH IT IS IMPOSSIBLE TO MOVE! So, if it seems IMPOSSIBLE, hit S to swap turns. Or if you just feel like switching turns... I guess.. Play with a friend! Inspired by the board game Othello. Also known as reversi. --- COULD have been 1 sprite 1 script, but I didn't wanna deal with the laggy-ness of pasting the same script in more than 5 places. So I used "Broadcast" blocks instead. That's why there are TWO scripts. Thanks. PRESS LOVE IT!
