BreOl72: My main concern is that the gameplay looks a tad repetitive..?
Basically, you move in a new location, get caught, so you rewind time and try it again, get caught someplace else, try again...until you've figured out the whole level.
There were a few levels that felt like this, but most of the time when you get caught it's because of silly things like you were standing slightly too close to the guard or ran out too soon and should have waited. There are a handful of levels where the guards have erratic patrol patterns and the level comes down to just figuring out where the blind spots are, but few enough that I didn't have a problem with it.
Having completed the game, my big complaint is that it's too easy and too short. I finished the entire game in two sittings, collecting 60% of the secrets without actively looking for them, and there were only a handful of levels that presented any real challenge. While I enjoyed the game, it was just too fleeting to leave a big impact for me.
