Click on your side to signal your turn is over and the other side will start counting
down.
If your side counts down to zero, the lower number will start counting up how many seconds
you have exceeded your allocated time. This value is preserved across turns. It is up to you to
interpret this number and penalize each side accordingly.
Pause will pause the game in whatever state it is in. Click the button again to
resume.
Reset will completely clear all counters. As a safety, you must be in paused mode while you
hit reset.
The keys [1234qwerasdfzxcv] have the same effect as clicking on the left side.
The keys [890uiopjklnm] have the same effect as clicking on the right side.
If you want to reset the counter just for the current turn, just end your turn and then end
the opponent's turn so it comes back to you with a full turn.
