I really like this concept, and the art/audio work together well too! I enjoyed the puzzle aspect to the game, and I enjoyed how easy it was to trap guards in corners, though I kind of doubt that was intentional. I saw someone else also had this issue, but I did get stuck in the same guard spawning pit. I realized a little too late that I was meant to rewind out of the pit, and was stuck in there until I got bored enough to spawn so many guards the game was suffering. Other than that, I think the idea works really well and was well executed! Well done.
