Innovative.
I have never seen a game like this, not to this level. it was very "Portal"esque, with the ignorance. i just followed the puzzles, which were not to difficult, but required some thought. the game was fantastic, indescribably, and the ending was even better. if i don't see a sequel, i will probably smash my computer Lol, i'm flabbergasted by the sheer genius of this game.
