Really liked the game. It's a neat little concept executed very well, and quite enjoyable putting the pieces together. It's even quite approachable and understandable for non-gamers to have a go at.
Cool concept and decent implementation, but given that it takes me about a minute to line up one photo. 2 minutes is way to short for a time limit. Setting the time limit to 3 or 4 minutes would make this alot more playable.
