Been playing for a few hours. Game just oozes style and personality. At first it seems like a simple Contra knockoff with some rewind elements thrown in but then you play more and see how integral the time travel ability is to the game, how you master each level by doing it and you realize how good it is.
My favorite part is unlocking new characters. You can either save them when you stumble upon them or you also unlock these shards throughout each level and one actually gives you a time limit where if you rewind all the way back to the level, you have, say, 35 seconds to make it back to that spot before the time portal closes and that character is gone. What it does is it allows them to make the time element almost required to beat the levels, but also gives hardcore players who want a "clean run" aspect a shot and great incentive.
Bravo to MS for scooping this up and bringing it to Xbox.
