Very nice puzzle game, I liked the mechanics and the humorous headlines between each level.
UX wise I would love it if when you're placing a prisoner block on top of another already placed prisoner block, rather than blocking you with a buzzer sound, it would swap the two pieces (so the piece you are holding is now in the jail, and the piece that was in the jail is now in your hand)
The music... I know that from somewhere, but where? It's not gillbert & sullivan... oh, this is going to bug me.
