Like PbnjGuy said, the connection to the theme doesn't pop out right away and isn't that fitting. But i had fun playing it and i like the puzzle like design.
I was initially suprised by that, but now I see that you need to get to level 7-8 for rewinding to really hit close to home and see that it is necessary to win easy mode.
Oh well, my rebalancing had the opposite effect of what I intended it to do.
