Being able to detach your head and use it to scout is an interesting concept. There were times when it didn't want to return to me, and I'm not sure if I was doing something wrong or if there was a bug. I do think the controls were a little difficult, since scouting usually involves dropping the head down a pit, and managing the jump and releasing the head took some time to get right.
This gets me thinking about what other types of interaction could exist with the detaching head concept. I think demonstrates potential, but is rough in it's current state.
