Table of Ordinary Status
left	central	right

Status bar table is a table-name that varies. Status bar table is the Table of Ordinary Status.

Right alignment depth is a number that varies. Right alignment depth is 14.

Use undo prevention.

The maximum score is 2.

The thyme count is a number variable. The thyme count is 0.

The secondary thyme count is a number variable. The secondary thyme count is 0.

The computer count is a number variable. The computer count is 0.

The nothing count is a number variable. The nothing count is 0.

Understand "weight" as weighting. Weighting is an action applying to nothing.

Report weighting:
	if the thyme count is 0:
		say "Thyme passes.";
		now the thyme count is 1;
		the thymegoing happens in one turn from now;
	otherwise:
		say "Thyme passes."

At the time when the thymegoing happens:
	now the thyme count is 0;

Understand the command "eat thyme" as something new. Understand the command "eat the thyme" as something new. Understand "eat thyme" or "eat the thyme" as thymeeating. Thymeeating is an action applying to nothing.

Report thymeeating:
	if the thyme count is 0:
		say "You can't see any such thing.";
	otherwise:
		if the secondary thyme count is 1:
			say "You eat the thyme as it passes. It nourishes your health.";
		otherwise:
			say "You eat the thyme as it passes. It nourishes your health.";
			increase the score by 1;
			now the secondary thyme count is 1;

Understand "type the right combination" or "the right combination" or "right combination" as safeopening. Safeopening is an action applying to nothing.

Report safeopening in The Second Room:
	if the safe is locked:
		now the safe is unlocked;
		now the safe is open;
		say "You open the safe. Inside you find a purple key.";
	otherwise:
		say "The safe is already open.";

Report safeopening in a room which is not The Second Room:
	say "I didn't understand that sentence."

The The Room Where Play Begins is a room. "You are in a room. This room is a very roomy room. In fact, the roominess of this roomy room is roomier than the roominess of many other roomy rooms."

Instead of doing something to nothing while the nothing count is 0:
	say "You're being crazy. Pull yourself together.";

There is a green key in the Garden.

Instead of dropping the vase:
	if the player carries the vase:
		say "The vase shatters at your feet from being dropped from a high altitude. A yellow key lies at your feet, presumably the object that was inside the vase.";

	pause the game;
	clear only the main screen;
	now everything carried by the player is in Storage;
	now the player is in the Garden;
	now the computer count is 1;

After the player taking the green key:
	say "You take the key in the game as you walk away from the computer. ";
	pause the game;
	clear only the main screen;
	now the player is in The Third Room;
	now the player carries everything that is in Storage;

Every turn:
	if the player is in The Fourth Room:
		say "[command prompt]";
		wait for any key;
		say "g";
		wait for any key;
		say "o ";
		wait for any key;
		say "t";
