Years ago, I wanted to make a simple app to test my skills learning web development. So I built a chess clock since I was learning chess at the time. It's a simple two-player timer that switches between players when you press a button.

1. Set a time that each player should be allotted (in minutes and seconds)
2. Press Start to begin the game
3. When a player completes their move, press spacebar or enter on the keyboard to switch to the other player's timer. (On mobile, tap the Switch button.)
4. The game ends when one player's time runs out.
