Very cool concept! I love the use of the limitation - at first I was frustrated that villagers were plunging to their deaths but then it clicked for me that this was inevitable.
The music was absolutely great. My biggest critiques are that the hand should move faster than it does, it feels very sluggish to control. Also, it would have been nice to slow down the pace of the villagers at the beginning while I got my bearings.
Overall very cool, loved the use of theme. Nice work!
