Well, I may have found a real winner on Newgrounds, a little game called Nanobot.  I may have, but I clearly didn’t.  Here–check out the clearly dysfunctional plot synopsis, provided, verbatim, by Nanobot itself:

“Your inside some computer monster. Find important system files to this monster, and release them through the monster’s bodily releases”

Yeah.  That’s the whole game. Find two computer files, drop them in its colon and urinary bladder and let nature do the rest.  You have infinite lives in which to accomplish this feat of excretion, and you may need them because the control scheme is unpleasant and the physics are downright tricky. The question of course is WHY.  As in, why bother?  Or, why does this garbage even exist, anyway?  Or, why haven’t this game’s creators been exiled to some small island where they can play with their feces all they clearly wish to?  The only downside is that to compare this game to the “excretory elements” featured throughout the game is both spectacularly fitting and entirely TOO EASY.

Too many unanswered whys for my taste, folks–pass this one on by.
