I like it. Had to play about half a dozen times before I realized why I was dying. And I wasn't sure if I had actually picked up the key or done anything with the safe.
But the mechanics are solid and the time-line viewing is neat. It's a pretty fun little puzzler.
I think I just brute-forced it until I stumbled into items in the right order rather than getting clever with counting the turns and the power and the FOV.
