Have you played the game Portal? This games seems almost exactly like that in some ways.
It's funny at the beginning and epic at the end, you don't want it to be over, it has some of the best game-play mechanics in its genre, and you deserve 50,000 cookies for making it.
Overall best flash game of the millennium.
