I was frustrated at first, I had no motivation to explore. Then I found the first pedestal (orange), losing the respective shield and was impressed with what I felt. The feeling of sacrifice I supposed to feel became a little too real...no game has ever really done that for me. I remember smiling as I realized what I felt as I looked at the green pedestal thinking, "Am I ready?". I don't think I have been motivated by sacrifice in a game before. Its the act of giving away a piece of me (unlike most games where you just die and restart) that made me feel like I HAVE to accomplish something.
Good work. A little unexpected greatness. Its nice.
