Three Cows and Two Doors

Play it if: you wish to explore profound metaphysical ideas as interpreted through the fascinating medium of bovine coloration.

Don't play it if: you do not wish to achieve NIRVANA.

What an incredible and psychologically complex game!

The player starts in the first floor of a place called the Grand Tower. The objective is to reach the top of the tower. This is clearly symbolic of the cycles of reincarnation (samsara) as espoused by mainstream Hinduism - as the immortal soul (the player, who can restart the game endlessly and never find an actual solution to the game). The Hindu connection can be conclusively established by the presence of cows in the starting room (though the fact that one of the doors is called Exit might suggest an alternative interpretation along the lines of Jean-Paul Sartre's work).

There are all sorts of details to be interpretively explored here. Why the particular colors of Pink, Green, and Purple? Why is it that examining the Pink and Purple Cows yields the tautology "X Cow is an x cow", while examining the Green Cow produces the statement "You see nothing special about Green Cow"? Or why is the description of Orange Door "The Orange Door is an orange door", while the description of the Exit is "You might be able to exit this way, if, that isn't, the exit wasn't locked". Why the phrase "that isn't"? Surely a game of this caliber couldn't have meant it as a glaring typo easily fixable by even the most basic proofreading process or input of creative effort, but must have some deeper meaning.

But then, who am I to interpret such things?

Perhaps the fact that nothing but three cows and two locked doors are implemented is a sign from the Author, a sign that we must not be troubled with the things of material existence, but must rather look to a higher purpose that exists behind the veneer of a simple interactive fiction game.

Namely, that the whole thing is a brutal waste of your time, the author is likely trolling, and your only path to spiritual liberation - moksha - is to free yourself of the need to play this game at all.
