Unnamed Google Easter Egg

For an easter egg, this is a pretty substantial game. It has dozens of rooms and half a dozen puzzles.

The game uses a restricted verb-only parser. "grab" to pick up objects, "use" to use one of your inventory items. I think this undermines a little bit of the fun of puzzle solving; if you reach a puzzle and you have the right inventory item, you can usually auto-solve the puzzle just by typing "use." If "use" doesn't work, you just have to fully explore all of the rooms, "grab" everything that isn't nailed down, and come back and "use" again.

(It also includes a "why" command that just prints random cute messages.)

The game includes a built-in ASCII map, but I found the map illegible, not least because it's full of symbols that aren't defined in the legend. (It doesn't help at all that the game starts by giving you a partial map, then briefly reveals a full map, and immediately takes it away. What's the point of that?)

For the record, the full legend should include:

(Spoiler - click to show)//, \\, and = means a walkway or bridge.
^ means a skybridge, which connects to another ^
~ means a body of water (impassible)
< means a room containing an elevator going up or down
