A traditional Chess Clock! All you need now is a set. :3 Includes a special "Lifeshare" Mode! If your timer goes into negative numbers, (a bug I'll have to fix,) you lose and your opponent wins. After you've made your move, HOLD, very important that you HOLD on your letter (see below) until the timer is passed on to your opponent. White's letter: W Black's letter: B Have Fun!
