I really liked the game. Loved the atmosphere, music, and it has a good story. It was short, but really, I think it's the right length for what it is. And it was refreshing to play a good story-driven game that wasn't based on killing a zillion enemies (says the guy about to go back to playing Diablo III). Contrast is up there with Beyond Good and Evil as one of my favorite XBlive Arcade games.
I did see the floating girl effect just outside the bedroom window once over three play throughs; but no where else in the game. And I got Dawn stuck once while going for the umbrella in the chest and came off the stage there. That was the only time Dawn got stuck in the environment that pressing (B) didn't get her out of. But there was a lot of wonky collision response through out.
