I have climbed through the elaborate caverns, endured the treacherous mechanics, experienced a hundred lives, and I met the elusive albino grinch, gaining its respect after it pulled a GLaDOS.
A folly claim you say? Well as far as you know, it could have been... because I'm lacking proof due to the fact that the medals didn't go off.
It appeared in the game, but after a certain point, it stopped. Granted, I did leave the page a few times to give myself a break from it, but I don't think it has anything to do with that.
That cavern atmosphere is met with this game and the mechanic are nice too, but only at first as it gets under your skin after a while. I guess it fits with the game, but trying to perform perfect jumps off of walls are difficult. Throwing the anchor mid flight is tolerable (if not, a bit tricky), but making these leaps of faith is ridiculous as you need to make your best judgement of when to dethatch the anchor or even if you think you're going the right direction.
The game is still good, hardcore players would probably have more fun with this than casual players. It has a mid-high range in difficulty, and it increases in leaps and bounds the higher up you go.
-----------------------
Interesting thing I need to note though, pressing the 'R' key resets the entire game and doesn't reset you to the last campfire. This could lead to some furious players if they accidently push it.

EDIT: Well say that I'm a glutton for punishment, but I went through it again. Used prior experience to zip though the place, saw some of the changes you made, cursed the heavens for the added obstacle in the secret path, and somehow met up with the white devil again. I checked to see if the medal activated, it did (yays), and as I clicked the screen to reestablish control to begin my escape, the game goes black. ...oy vey.
