The idea to implement the trolley problem as the theme for a game is pretty nice. I also really liked your presentation and the body switching controls. :)
It just didn't feel much like an out of control situation when you are able to move the one piece out of the way. Maybe it would feel more out of control if it would be more difficult or impossible to resolve the situation?
But nonetheless really great work and the game feels super polished in its simplistic presentation!
