Play chess! If there is already a game going on, you can spectate. How do you move the chess pieces? Just click one of your pieces, then click where you want the piece to go! If it isn't going there, it's either not your turn, that piece can't go there, or Cloud Data is lagging and you have to redo your move again. You can reset the board with R, but the other player needs to press R as well, and I haven't made anything yet that notifies them when they must confirm a reset.
Everything but the chess sprites is by me. Here's the forum thread for this game by the way: https://scratch.mit.edu/discuss/topic/125250/ Currently, because I was in a rush to release this ASAP: - The game won't end when the king is taken, so you'll have to manually reset the board with R. - Castling doesn't exist yet.
